Dual AGN in the Horizon-AGN simulation and their link to galaxy and massive black hole mergers, with an excursus on multiple AGN
Marta Volonteri, Hugo Pfister, Ricarda Beckmann +5
The occurrence of dual active galactic nuclei (AGN) on scales of a few tens of kpc can be used to study merger-induced accretion on massive black holes (MBHs) and to derive clues o…
Supernova-driven turbulent metal mixing in high redshift galactic disks: metallicity fluctuations in the interstellar medium and its imprints on metal poor stars in the Milky Way
Anne Noer Kolborg, Davide Martizzi, Enrico Ramirez-Ruiz +4
The extent to which turbulence mixes gas in the face of recurrent infusions of fresh metals by supernovae (SN) could help provide important constraints on the local star formation…
Tidal disruption events in the first billion years of a galaxy
Hugo Pfister, Jane Dai, Marta Volonteri +3
Accretion of stars on massive black holes (MBHs) can feed MBHs and generate tidal disruption events (TDEs). We introduce a new physically motivated model to self-consistently treat…
Black hole mergers from dwarf to massive galaxies with the NewHorizon and Horizon-AGN simulations
Marta Volonteri, Hugo Pfister, Ricarda S. Beckman +12
Massive black hole (MBH) coalescences are powerful sources of low-frequency gravitational waves. To study these events in the cosmological context we need to trace the large-scale…
Enhancement of the tidal disruption event rate in galaxies with a nuclear star cluster: from dwarfs to ellipticals
Hugo Pfister, Marta Volonteri, Jane Lixin Dai +1
We compute the tidal disruption event (TDE) rate around local massive black holes (MBHs) with masses as low as , thus probing the dwarf regime for the…
The Obelisk simulation: galaxies contribute more than AGN to HI reionization of protoclusters
Maxime Trebitsch, Yohan Dubois, Marta Volonteri +9
We present the Obelisk project, a cosmological radiation-hydrodynamics simulation following the assembly and reionization of a protocluster progenitor during the first two billions…
Real galaxy mergers from galaxy pair catalogs
Hugo Pfister, Massimo Dotti, Clothilde Laigle +2
Mergers of galaxies are extremely violent events shaping their evolution. Such events are thought to trigger starbursts and, possibly, black hole accretion. Nonetheless, it is stil…
Tidal disruption event rates in galaxy merger remnants
Hugo Pfister, Ben Bar-Or, Marta Volonteri +2
The rate of tidal disruption events (TDEs) depends sensitively on the stellar properties of the central galactic regions. Simulations show that galaxy mergers cause gas inflows, tr…
The erratic dynamical life of black hole seeds in high-redshift galaxies
Hugo Pfister, Marta Volonteri, Yohan Dubois +2
The dynamics of black hole seeds in high redshift galaxies is key to understand their ability to grow via accretion and to pair in close binaries during galactic mergers. To proper…
The birth of a supermassive black hole binary
Hugo Pfister, Alessandro Lupi, Pedro R. Capelo +3
We study the dynamical evolution of supermassive black holes, in the late stage of galaxy mergers, from kpc to pc scales. In particular, we capture the formation of the binary, a n…
