Large-scale dual AGN in large-scale cosmological hydrodynamical simulations
Clara Puerto-Sánchez, Melanie Habouzit, Marta Volonteri +10
Detecting dual active galactic nuclei (DAGN) in observations and understanding theoretically which massive black holes (MBHs) compose them and in which galactic and large-scale env…
Dark Matter Mounds: towards a realistic description of dark matter overdensities around black holes
Gianfranco Bertone, A. Renske A. C. Wierda, Daniele Gaggero +3
Dark matter overdensities around black holes can be searched for by looking at the characteristic imprint they leave on the gravitational waveform of binary black hole mergers. Cur…
LISA Definition Study Report
Monica Colpi, Karsten Danzmann, Martin Hewitson +108
The Laser Interferometer Space Antenna (LISA) is the first scientific endeavour to detect and study gravitational waves from space. LISA will survey the sky for Gravitational Waves…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Assessing inflow rates in atomic cooling halos: implications for direct collapse black holes
M. A. Latif, M. Volonteri
Supermassive black holes are not only common in the present-day galaxies, but billion solar masses black holes also powered quasars. One efficient way to form such black…
Dancing in the dark: galactic properties trace spin swings along the cosmic web
Yohan Dubois, Christophe Pichon, Charlotte Welker +30
A large-scale hydrodynamical cosmological simulation, Horizon-AGN, is used to investigate the alignment between the spin of galaxies and the cosmic filaments above redshift 1.2. Th…
New observational Constraints on the Growth of the First Supermassive Black Holes
E. Treister, K. Schawinski, M. Volonteri +1
We constrain the total accreted mass density in supermassive black holes at z>6, inferred via the upper limit derived from the integrated X-ray emission from a sample of photometri…
Nuclear coups: dynamics of black holes in galaxy mergers
Sandor Van Wassenhove, Pedro R. Capelo, Marta Volonteri +4
We study the dynamical evolution of supermassive black holes (BHs) in merging galaxies on scales of hundreds of kpc to 10 pc, to identify the physical processes that aid or hinder…
The Relative Role of Galaxy Mergers and Cosmic Flows in Feeding Black Holes
Jillian Bellovary, Alyson Brooks, Marta Volonteri +3
Using a set of zoomed-in cosmological simulations of high-redshift progenitors of massive galaxies, we isolate and trace the history of gas that is accreted by central supermassive…
The role of relativistic jets in the heaviest and most active supermassive black holes at high redshift
G. Ghisellini, F. Haardt, R. Della Ceca +2
In powerful radio-quiet active galactic nuclei (AGN), black holes heavier than one billion solar masses form at a redshift ~1.5-2. Supermassive black holes in jetted radio-loud AGN…
Black hole evolution: III. Statistical properties of mass growth and spin evolution using large-scale hydrodynamical cosmological simulations
Yohan Dubois, Marta Volonteri, Joseph Silk
Supermassive black holes (BH) at the centres of galaxies can rapidly change their mass and spin by gas accretion and mergers. Using hydrodynamical cosmological simulations, with pr…
On the orientation and magnitude of the black hole spin in galactic nuclei
M. Dotti, M. Colpi, S. Pallini +2
Massive black holes in galactic nuclei vary their mass M and spin vector J due to accretion. In this study we relax, for the first time, the assumption that accretion can be either…
Massive black holes in central cluster galaxies
Marta Volonteri, Luca Ciotti
We explore how the co-evolution of massive black holes (MBHs) and galaxies is affected by environmental effects, addressing in particular MBHs hosted in the central galaxies of clu…
Black Holes in the Early Universe
Marta Volonteri, Jillian Bellovary
The existence of massive black holes was postulated in the sixties, when the first quasars were discovered. In the late nineties their reality was proven beyond doubt, in the Milky…
The first massive black holes
Marta Volonteri
I briefly outline recent theoretical developments on the formation of the first massive black holes (MBHs) that may grow into the population of MBHs powering quasars and inhabiting…
Limits on the high redshift growth of massive black holes
R. Salvaterra, F. Haardt, M. Volonteri +1
We place firm upper limits on the global accretion history of massive black holes at z>5 from the recently measured unresolved fraction of the cosmic X-ray background. The maximum…
The Formation and Evolution of Massive Black Holes
Marta Volonteri
The past 10 years have witnessed a change of perspective in the way astrophysicists think about massive black holes (MBHs), which are now considered to have a major role in the evo…
High-redshift formation and evolution of central massive objects II: The census of BH seeds
B. Devecchi, M. Volonteri, E. M. Rossi +2
We present results of simulations aimed at tracing the formation of nuclear star clusters (NCs) and black hole (BH) seeds, in a cosmological context. We focus on two mechanisms for…
eLISA: Astrophysics and cosmology in the millihertz regime
Pau Amaro-Seoane, Sofiane Aoudia, Stanislav Babak +27

Observability of Dual Active Galactic Nuclei in Merging Galaxies
Sandor Van Wassenhove, Marta Volonteri, Lucio Mayer +3
Supermassive black holes (SMBHs) have been detected in the centers of most nearby massive galaxies. Galaxies today are the products of billions of years of galaxy mergers, but also…
