Massive black hole seeds born via direct gas collapse in galaxy mergers: their properties, statistics and environment
Silvia Bonoli, Lucio Mayer, Simone Callegari
We study the statistics and cosmic evolution of massive black hole seeds formed during major mergers of gas-rich late-type galaxies. Generalizing the results of the hydro-simulatio…
Formation and Hardening of Supermassive Black Hole Binaries in Minor Mergers of Disk Galaxies
Fazeel Mahmood Khan, Ingo Berentzen, Peter Berczik +4
We model for the first time the complete orbital evolution of a pair of Supermassive Black Holes (SMBHs) in a 1:10 galaxy merger of two disk dominated gas-rich galaxies, from the s…
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…
Forming Realistic Late-Type Spirals in a LCDM Universe: The Eris Simulation
Javiera Guedes, Simone Callegari, Piero Madau +1
Simulations of the formation of late-type spiral galaxies in a cold dark matter LCDM universe have traditionally failed to yield realistic candidates. Here we report a new cosmolog…
Tidal stirring of Milky Way satellites: a simple picture with the integrated tidal force
Ewa L. Lokas, Stelios Kazantzidis, Lucio Mayer +1
Most of dwarf spheroidal galaxies in the Local Group were probably formed via environmental processes like the tidal interaction with the Milky Way. We study this process via N-bod…
On the Efficiency of the Tidal Stirring Mechanism for the Origin of Dwarf Spheroidals: Dependence on the Orbital and Structural Parameters of the Progenitor Disky Dwarfs
Stelios Kazantzidis, Ewa L. Lokas, Simone Callegari +2
(Abridged) The tidal stirring model posits the formation of dSph galaxies via the tidal interactions between rotationally-supported dwarfs and MW-sized host galaxies. Using a set o…
Growing Massive Black Hole Pairs in Minor Mergers of Disk Galaxies
S. Callegari, S. Kazantzidis, L. Mayer +4
We perform a suite of high-resolution smoothed particle hydrodynamics simulations to investigate the orbital decay and mass evolution of massive black hole (MBH) pairs down to scal…
Direct Formation of Supermassive Black Holes via Multi-Scale Gas Inflows in Galaxy Mergers
Lucio Mayer, Stelios Kazantzidis, Andres Escala +1
Observations of distant bright quasars suggest that billion solar mass supermassive black holes (SMBHs) were already in place less than a billion years after the Big Bang. Models i…
