Dynamics and spin alignment in massive, gravito-turbulent circumbinary discs around supermassive black hole binaries
Martin A. Bourne, Davide Fiacconi, Debora Sijacki +2
Parsec-scale separation supermassive black hole binaries in the centre of gas-rich galaxy merger remnants could be surrounded by massive circumbinary discs (CBDs). Black hole mass…
Stellar and Weak Lensing Profiles of Massive Galaxies in the Hyper-Suprime Cam Survey and in Hydrodynamic Simulations
Felipe Ardila, Song Huang, Alexie Leauthaud +11
We perform a consistent comparison of the mass and mass profiles of massive () central galaxies at z~0.4 from deep Hyper Suprime-Cam (HSC) observation…
Galactic nuclei evolution with spinning black holes: method and implementation
Davide Fiacconi, Debora Sijacki, J. E. Pringle
Supermassive black holes at the centre of galactic nuclei mostly grow in mass through gas accretion over cosmic time. This process also modifies the angular momentum (or spin) of b…
Constraining the mass of accreting black holes in ultraluminous X-ray sources with ultrafast outflows
Davide Fiacconi, Ciro Pinto, Dominic J. Walton +1
The nature of ultraluminous X-ray sources (ULXs) -- off-nuclear extra-galactic sources with luminosity, assumed isotropic, erg s -- is still debated. One p…
Young and turbulent: the early life of massive galaxy progenitors
Davide Fiacconi, Lucio Mayer, Piero Madau +3
We present results from the "Ponos" simulation suite on the early evolution of a massive, M galaxy. At , before feedback f…
Light or heavy supermassive black hole seeds: the role of internal rotation in the fate of supermassive stars
Davide Fiacconi, Elena M. Rossi
Supermassive black holes are a key ingredient of galaxy evolution. However, their origin is still highly debated. In one of the leading formation scenarios, a black hole of $\sim10…
Swift coalescence of supermassive black holes in cosmological mergers of massive galaxies
Fazeel M. Khan, Davide Fiacconi, Lucio Mayer +2
Supermassive black holes (SMBHs) are ubiquitous in galaxies with a sizable mass. It is expected that a pair of SMBHs originally in the nuclei of two merging galaxies would form a b…
Cold Dark Matter Substructures in Early-Type Galaxy Halos
Davide Fiacconi, Piero Madau, Doug Potter +1
We present initial results from the "Ponos" zoom-in numerical simulations of dark matter substructures in massive ellipticals. Two very highly resolved dark matter halos with $M_{\…
Bar-formation as driver of gas inflows in isolated disc galaxies
R. Fanali, M. Dotti, D. Fiacconi +1
Stellar bars are a common feature in massive disc galaxies. On a theoretical ground, the response of gas to a bar is generally thought to cause nuclear starbursts and, possibly, AG…
Bright vigorous winds as signposts of supermassive black hole birth
Davide Fiacconi, Elena M. Rossi
The formation of supermassive black holes is still an outstanding question. In the quasi-star scenario, black hole seeds experience an initial super-Eddington growth, that in less…
Direct formation of supermassive black holes in metal-enriched gas at the heart of high-redshift galaxy mergers
Lucio Mayer, Davide Fiacconi, Silvia Bonoli +4
We present novel 3D multi-scale SPH simulations of gas-rich galaxy mergers between the most massive galaxies at , designed to scrutinize the direct collapse formatio…
The Argo Simulation: II. The Early Build-up of the Hubble Sequence
Davide Fiacconi, Robert Feldmann, Lucio Mayer
The Hubble sequence is a common classification scheme for the structure of galaxies. Despite the tremendous usefulness of this diagnostic, we still do not fully understand when, wh…
Orbital Decay of Supermassive Black Hole Binaries in Clumpy Multiphase Merger Remnants
R. Roškar, L. Mayer, D. Fiacconi +3
We simulate an equal-mass merger of two Milky Way-size galaxy discs with moderate gas fractions at parsec-scale resolution including a new model for radiative cooling and heating i…
Massive black hole pairs in clumpy, self-gravitating circumnuclear disks: stochastic orbital decay
Davide Fiacconi, Lucio Mayer, Rok Roskar +1
We study the dynamics of massive black hole pairs in clumpy gaseous circumnuclear disks. We track the orbital decay of the light, secondary black hole orbiting aroun…
Adaptive mesh refinement simulations of collisional ring galaxies: effects of the interaction geometry
Davide Fiacconi, Michela Mapelli, Emanuele Ripamonti +1
Collisional ring galaxies are the outcome of nearly axisymmetric high-speed encounters between a disc and an intruder galaxy. We investigate the properties of collisional ring gala…
