Massive black hole and gas dynamics in galaxy nuclei mergers. I. Numerical implementation
Alessandro Lupi, Francesco Haardt, Massimo Dotti
Numerical effects are known to plague adaptive mesh refinement (AMR) codes when treating massive particles, e.g. representing massive black holes (MBHs). In an evolving background,…
New insights on the recoiling/binary black hole candidate J0927+2943 via molecular gas observations
Roberto Decarli, Massimo Dotti, Chiara Mazzucchelli +2
The peculiar QSO J0927+2943 shows multiple sets of emission lines in its optical spectrum. This signature has been interpreted as the relative motion between a black hole, either r…
Growth and activity of black holes in galaxy mergers with varying mass ratios
Pedro R. Capelo, Marta Volonteri, Massimo Dotti +3
We study supermassive black holes (BHs) in merging galaxies, using a suite of hydrodynamical simulations with very high spatial (~10 pc) and temporal (~1 Myr) resolution, where we…
The nature of massive black hole binary candidates: II. Spectral energy distribution atlas
Elisabeta Lusso, Roberto Decarli, Massimo Dotti +5
Recoiling supermassive black holes (SMBHs) are considered one plausible physical mechanism to explain high velocity shifts between narrow and broad emission lines sometimes observe…
Super-Critical Growth of Massive Black Holes from Stellar-Mass Seeds
Piero Madau, Francesco Haardt, Massimo Dotti
We consider super-critical accretion with angular momentum onto stellar-mass black holes as a possible mechanism for growing billion-solar-mass holes from light seeds at early time…
Linking the spin evolution of massive black holes to galaxy kinematics
Alberto Sesana, Enrico Barausse, Massimo Dotti +1
We present the results of a semianalytical model that evolves the masses and spins of massive black holes together with the properties of their host galaxies along the cosmic histo…
