Summary Most celestial bodies, from planets, to stars, to black holes; gain mass during their lives by means of an accretion disc. Understanding the physical processes that determine the rate at which matter accretes and energy is radiated in these discs is vital for unraveling the formation, evolution, and fate of almost every type of object in the Universe. Despite the fact that magnetic fields have been known to be crucial in accretion discs since the early 90’s, the majority of astrophysical questions that depend on the details of how disc accretion proceeds are still being addressed using the “standard” accretion disc model (developed in the early 70’s), where magnetic fields do not play an explicit role. This has prevented us from fully exploring the astrophysical consequences and observational signatures of realistic accretion disc models, leading to a profound disconnect between observations (usually interpreted with the standard paradigm) and modern accretion disc theory and numerical simulations (where magnetic turbulence is crucial). The goal of this proposal is to use several complementary approaches in order to finally move beyond the standard paradigm. This program has two main objectives: 1) Develop the theoretical framework to incorporate magnetic fields, and the ensuing turbulence, into self-consistent accretion disc models, and investigate their observational implications. 2) Investigate transport and radiative processes in collision-less disc regions, where non-thermal radiation originates, by employing a kinetic particle description of the plasma. In order to achieve these goals, we will use, and build upon, state-of-the-art magnetohydrodynamic and particle-in-cell codes in conjunction with theoretical modeling. This framework will make it possible to address fundamental questions on stellar and planet formation, binary systems with a compact object, and supermassive black hole feedback in a way that has no counterpart within the standard paradigm.

Project Algorithmic Finance: Inquiring into the Reshaping of Financial Markets
Researcher (PI) Christian BORCH
Host Institution (HI) COPENHAGEN BUSINESS SCHOOL
Call Details Consolidator Grant (CoG), SH3, ERC-2016-COG
Summary Present-day financial markets are turning algorithmic, as market orders are increasingly being executed by fully automated computer algorithms, without any direct human intervention. Although algorithmic finance seems to fundamentally reshape the central dynamics in financial markets, and even though it prompts core sociological questions, it has not yet received any systematic attention. In a pioneering contribution to economic sociology and social studies of finance, ALGOFINANCE aims to understand how and with what consequences the turn to algorithms is changing financial markets. The overall concept and central contributions of ALGOFINANCE are the following: (1) on an intra-firm level, the project examines how the shift to algorithmic finance reshapes the ways in which trading firms operate, and does so by systematically and empirically investigating the reconfiguration of organizational structures and employee subjectivity; (2) on an inter-algorithmic level, it offers a ground-breaking methodology (agent-based modelling informed by qualitative data) to grasp how trading algorithms interact with one another in a fully digital space; and (3) on the level of market sociality, it proposes a novel theorization of how intra-firm and inter-algorithmic dynamics can be conceived of as introducing a particular form of sociality that is characteristic to algorithmic finance: a form of sociality-as-association heuristically analyzed as imitation. None of these three levels have received systematic attention in the state-of-the-art literature. Addressing them will significantly advance the understanding of present-day algorithmic finance in economic sociology. By contributing novel empirical, methodological, and theoretical understandings of the functioning and consequences of algorithms, ALGOFINANCE will pave the way for other research into digital sociology and the broader algorithmization of society.

Project acronym ASTERISK
Project ASTERoseismic Investigations with SONG and Kepler
Researcher (PI) Jørgen Christensen-Dalsgaard
Host Institution (HI) AARHUS UNIVERSITET
Call Details Advanced Grant (AdG), PE9, ERC-2010-AdG_20100224
Summary The project aims at a breakthrough in our understanding of stellar evolution, by combining advanced observations of stellar oscillations with state-of-the-art modelling of stars. This will largely be based on very extensive and precise data on stellar oscillations from the NASA Kepler mission launched in March 2009, but additional high-quality data will also be included. In particular, my group is developing the global SONG network for observations of stellar oscillations. These observational efforts will be supplemented by sophisticated modelling of stellar evolution, and by the development of asteroseismic tools to use the observations to probe stellar interiors. This will lead to a far more reliable determination of stellar ages, and hence ages of other astrophysical objects; it will compare the properties of the Sun with other stars and hence provide an understanding of the life history of the Sun; it will investigate the physical processes that control stellar properties, both at the level of the thermodynamical properties of stellar plasmas and the hydrodynamical instabilities that play a central role in stellar evolution; and it will characterize central stars in extra-solar planetary systems, determining the size and age of the star and hence constrain the evolution of the planetary systems. The Kepler data will be analysed in a large international collaboration coordinated by our group. The SONG network, which will become partially operational during the present project, will yield even detailed information about the conditions in the interior of stars, allowing tests of subtle but central aspects of the physics of stellar interiors. The projects involve the organization of a central data archive for asteroseismic data, at the Royal Library, Copenhagen.

Project Beasts to Craft: BioCodicology as a new approach to the study of parchment manuscripts
Researcher (PI) Matthew COLLINS
Host Institution (HI) KOBENHAVNS UNIVERSITET
Call Details Advanced Grant (AdG), SH6, ERC-2017-ADG
Summary The intention of Beasts to Craft (B2C) is to document the biological and craft records in parchment in order to reveal the entangled histories of animal improvement and parchment production in Europe from 500-1900 AD.
B2C will lay the foundations for a new approach to the the study of parchment manuscripts —biocodicology— which draws evidence from the overlooked first stages in production, the raising of livestock and the preparation of the skins.
1. Parchment is an extraordinary but overlooked high resolution zooarchaeological record and a molecular archive. Livestock genetics is revealing breed diversity and markers of character traits such as fleece quality. B2C will exploit this new-found knowledge, using progressively older dated archival (sheep) parchments to study the history of improvement 1300 - 1900. Visual examination of the skins will search for direct evidence of disease and fleece quality.
2. Craft skills can be read from parchment and, when combined with chemical data and comparison with modern analogues, will produce the first European wide record of the craft from 500-1900. The size and scope of this the parchment archive means it is one of the largest and most highly resolved records of a specialist medieval craft. We will explore how these skills develop and when and where regional patterns appear and decline.
These two remarkable records requires a large interdisciplinary team. However biocodicology draws from and informs upon a wide and diverse spectrum of existing scholarship in conservation, the arts and sciences. A third strand of the project will (i) furnish manuscript scholars with some of the information available to the scribe at time of production (ii) inform and shape attitudes to parchment conservation (iii) provide high resolution biological data on animal management, movement and health and (iv) explore methods to link datasets and promote data reuse.

Project “Between the Times”: Embattled Temporalities and Political Imagination in Interwar Europe
Researcher (PI) Liisi KEEDUS
Host Institution (HI) TALLINN UNIVERSITY
Call Details Starting Grant (StG), SH6, ERC-2017-STG
Summary The proposed project offers a new, pan-European intellectual history of the political imagination in the interwar period that places the demise of historicism and progressivism – and the emerging anti-teleological visions of time – at the center of some of its most innovative ethical, political and methodological pursuits. It argues that only a distinctively cross-disciplinary and European narrative can capture the full ramifications and legacies of a fundamental rupture in thought conventionally, yet inadequately confined to the German cultural space and termed “anti-historicism”. It innovates narratively by exploring politically and theoretically interlaced reinventions of temporality across and between different disciplines (theology, jurisprudence, classical studies, literary theory, linguistics, sociology, philosophy), as well as other creative fields. It experiments methodologically by reconstructing the dynamics of political thought prosopographically, through intellectual groupings at the forefront of the scholarly and political debates of the period. It challenges the sufficiency of the standard focus in interwar intellectual history on one or two, at most three (usually “Western” European) national contexts by following out the interactions of these groupings in France, Britain, Germany, Russia, Czechoslovakia, and Romania – groupings whose members frequently moved across national contexts. What were the political languages encoded in the reinventions of time, and vice versa – how were political aims translated into and advanced through theoretical innovation? How did these differ in different national contexts, and why? What are the fragmented legacies of this rupture, disbursed in and through the philosophical, methodological and political dicta and dogmas that rooted themselves in post-1945 thought? This project provides the first comprehensive answer to these fundamental questions about the intellectual identity of Europe and its historicities.

Project Development of functional organization of the visual circuits in mice
Researcher (PI) Keisuke Yonehara
Host Institution (HI) AARHUS UNIVERSITET
Call Details Starting Grant (StG), LS5, ERC-2014-STG
Summary The key organizing principles that characterize neuronal systems include asymmetric, parallel, and topographic connectivity of the neural circuits. The main aim of my research is to elucidate the key principles underlying functional development of neural circuits by focusing on those organizing principles. I choose mouse visual system as my model since it contains all of these principles and provides sophisticated genetic tools to label and manipulate individual circuit components. My research is based on the central hypothesis that the mechanisms of brain development cannot be fully understood without first identifying individual functional cell types in adults, and then understanding how the functions of these cell types become established, using cell-type-specific molecular and synaptic mechanisms in developing animals. Recently, I have identified several transgenic mouse lines in which specific cell types in a visual center, the superior colliculus, are labeled with Cre recombinase in both developing and adult animals. Here I will take advantage of these mouse lines to ask fundamental questions about the functional development of neural circuits. First, how are distinct sensory features processed by the parallel topographic neuronal pathways, and how do they contribute to behavior? Second, what are the molecular and synaptic mechanisms that underlie developmental circuit plasticity for forming parallel topographic neuronal maps in the brain? Third, what are the molecular mechanisms that set up spatially asymmetric circuit connectivity without the need for sensory experience? I predict that my insights into the developmental mechanism of asymmetric, parallel, and topographic connectivity and circuit plasticity will be instructive when studying other brain circuits which contain similar organizing principles.

Project Classical Influences and Irish Culture
Researcher (PI) Isabelle Torrance
Host Institution (HI) AARHUS UNIVERSITET
Call Details Consolidator Grant (CoG), SH5, ERC-2018-COG
Summary The hypothesis of this project is that Ireland has a unique and hitherto underexplored history of cultural engagement with models from ancient Greece and Rome. Unlike Britain and mainland Europe, Ireland was never part of the Roman Empire. Yet the island has an extraordinarily vibrant tradition of classical learning that dates back to its earliest recorded literature, and is unparalleled in other northern European countries. Research for this project will address why this is the case, by examining sources through nine significant diachronic themes identified by the PI: language; land; travel and exile; Troy; satire; Neoplatonism; female voices; material culture; and global influence. This multi-thematic approach will enable analysis of what is remarkable about classical reception in Ireland. It will also provide a heuristic framework that generates dialogue between normally disparate fields, such as classical reception studies, Irish and British history, English-language literature, Irish-language literature, medieval studies, postcolonial studies, philosophy, material culture, women's studies, and global studies. The project will engage with contemporary preoccupations surrounding the politics and history of the divided island of Ireland, such as the current decade of centenary commemorations for the foundation of an independent Irish state (1912-1922, 2012-2022), and the on-going violence and political divisions in Northern Ireland. These issues will serve as a springboard for opening new avenues of investigation that look far beyond the past 100 years, but are linked to them. The project will thus shed new light on the role of classical culture in shaping literary, social, and political discourse across the island of Ireland, and throughout its history.

Project Cliodynamic archaeology: Computational approaches to Final Palaeolithic/earliest Mesolithic archaeology and climate change
Researcher (PI) Felix RIEDE
Host Institution (HI) AARHUS UNIVERSITET
Call Details Consolidator Grant (CoG), SH6, ERC-2018-COG
Summary Late Pleistocene/early Holocene Europe is said to be the ideal laboratory for the investigation of human responses to rapidly changing climates and environments, migration and adaptation. Yet, pinpointing precisely how and why contemporaneous Final Palaeolithic/earliest Mesolithic (15,000-11,000 years BP) foragers migrated, and which environmental or other factors they adapted to – or failed to – has remained remarkably elusive. At the core of ClioArch is the radical but, in light of research-historical insights, necessary hypothesis that the current archaeological cultural taxonomy for this iconic period of European prehistory is epistemologically flawed and that operationalisations and interpretations based on this traditional taxonomy – especially those that seek to relate observed changes in material culture and land-use to contemporaneous climatic and environmental changes – are therefore problematic. Hence, novel approaches to crafting the taxonomic building blocks are required, as are novel analyses of human|environment relations in this period. ClioArch’s premier ambition is to provide operational cultural taxonomies for the Final Palaeolithic/earliest Mesolithic of Europe and to couple these with interdisciplinary cultural evolutionary, quantitative ecological methods and field archaeological investigations beyond the state-of-the-art, so as to better capture such adaptations – almost certainly with major implications for the standard culture-historical narrative relating to this period. In so doing, the project will pioneer a fully transparent and replicable – and eminently transferable – methodology for the study of the impacts of climate change and extreme environmental events in deep history. In turn, such a quantitative understanding of past adaptive dynamics will position archaeology more centrally in contemporary debates about climate change, environmental catastrophe and their cultural dimensions.

Summary Advances in technology and methodology over the last decade, have enabled the study of galaxies to the highest redshifts. This has revolutionized our understanding of the origin and evolution of galaxies. I have played a central role in this revolution, by discovering that at z=2, when the universe was only 3 Gyr old, half of the most massive galaxies were extremely compact and had already completed their star formation. During the last five years I have led a successful group of postdocs and students dedicated to investigating the extreme properties of these galaxies and place them into cosmological context. Combining a series of high profile observational studies published by my group and others, I recently proposed an evolutionary sequence that ties together the most extreme galaxies in the universe, from the most intense dusty starburst at cosmic dawn, through quasars: the brightest sources in the universe, driven by feedback from supermassive black holes, and galaxy cores hosting the densest conglomerations of stellar mass known, to the sleeping giants of the local universe, the giant ellipticals. The proposed research program will explore if such an evolutionary sequence exists, with the ultimate goal of reaching, for the first time, a coherent physical understanding of how the most massive galaxies in the universe formed. While there is a chance the rigorous tests may ultimately reveal the proposed sequence to be too simplistic, a guarantied outcome of the program is a significantly improved understanding of the physical mechanisms that shape galaxies and drive their star formation and quenching

Project Design Global, Manufacture Local: Assessing the Practices, Innovation, and Sustainability Potential of an Emerging Mode of Production
Researcher (PI) Vasileios KOSTAKIS
Host Institution (HI) TALLINNA TEHNIKAULIKOOL
Call Details Starting Grant (StG), SH2, ERC-2018-STG
Summary COSMOLOCALISM will document, analyse, test, evaluate, and create awareness about an emerging mode of production, based on the confluence of the digital commons (e.g. open knowledge and design) with local manufacturing and automation technologies (from 3D printing and CNC machines to low-tech tools and crafts). This convergence could catalyse the transition to new inclusive and circular productive models, such as the “design global, manufacture local” (DGML) model.
DGML describes the processes through which design is developed as a global digital commons, whereas the manufacturing takes place locally, through shared infrastructures and with local biophysical conditions in mind. DGML seems to form economies of scope that promote sustainability and open innovation while celebrating new ways of cooperation. However, such claims rest on thin conceptual and empirical foundations.
COSMOLOCALISM is a multiphase, pilot-driven investigation of the DGML phenomenon that seeks to understand relevant organisational models, their evolution, and their broader political economy/ecology and policy implications. Through the lens of diverse case studies and participatory action research, the conditions under which the DGML model thrives will be explored.
COSMOLOCALISM has three concurrent streams: practices; innovation; and sustainability. First, DGML practices will be studied, patterns will be recognised and their form, function, cultural values, and governance structure will be determined. Second, the relevant open innovation ecosystems and their potential to reorient design and manufacturing practices will be examined. Third, selected DGML products will be evaluated from an environmental sustainability perspective, involving both qualitative and quantitative methods. The interdisciplinary nature of COSMOLOCALISM will explore new horizons to substantively improve our understanding of how we could do “more” and “better” with less.

Second, the relevant open innovation ecosystems and their potential to reorient design and manufacturing practices will be examined. Third, selected DGML products will be evaluated from an environmental sustainability perspective, involving both qualitative and quantitative methods. The interdisciplinary nature of COSMOLOCALISM will explore new horizons to substantively improve our understanding of how we could do “more” and “better” with less.
