Winds Against Alignment: AGN Feedback and the Spin Evolution of Massive Black Hole Binaries
Francesco Bollati, Marta Volonteri, Alessandro Lupi +2
The interaction between massive black hole (MBH) binaries and circumbinary discs (CBDs) affects the spin orientations of merging binaries - a key observable for the future LISA mis…
Spacetime in motion: an evolving relativistic binary black hole metric for GIZMO
Giacomo Fedrigo, Alessandro Lupi, Alessia Franchini +1
The last evolutionary stages of massive black hole binaries prior to coalescence is dominated by the emission of gravitational waves, which will be probed by the future Laser Inter…
The LISA Astrophysics "Disc-IMRI" Code Comparison Project: Intermediate-Mass-Ratio Binaries in AGN-Like Discs
Andrea Derdzinski, Alexander J. Dittmann, Alessia Franchini +16
Upcoming space-based gravitational wave detectors such as LISA, the Laser Interferometer Space Antenna, will be sensitive to extreme- and intermediate-mass-ratio inspirals (EMRIs a…
Suppressed "lump" EM signature in radiation pressure dominated accreting massive black hole binaries
Fabiola Cocchiararo, Alessia Franchini, Alessandro Lupi +1
We investigate the impact of radiation pressure on electromagnetic signatures of accreting massive black hole binaries (MBHBs) at milli-parsec separations, using 3D hyper-Lagrangia…
Identifying massive black hole binaries via light curve variability in optical time-domain surveys
Alfredo Chiesa, David Izquierdo-Villalba, Alberto Sesana +5
Accreting massive black hole binaries (MBHBs) often display periodic variations in their emitted radiation, providing a distinctive signature for their identification. In this work…
Radiation pressure role in accreting massive black hole binaries
Fabiola Cocchiararo, Alessia Franchini, Alessandro Lupi +1
We investigate the impact of radiation pressure on the circumbinary discs surrounding accreting massive black hole binaries (MBHBs) at milli-parsec separations, using 3D hyper-Lagr…
Gas-induced perturbations on the gravitational wave in-spiral of live post-Newtonian LISA massive black hole binaries
Mudit Garg, Alessia Franchini, Alessandro Lupi +2
We investigate the effect of dynamically coupling gas torques with gravitational wave (GW) emission during the orbital evolution of an equal-mass massive black hole binary (MBHB).…
Supermassive black hole formation via collisions in black hole clusters
Benjamin Gaete, Dominik R. G. Schleicher, Alessandro Lupi +3
More than 300 supermassive black holes have been detected at redshifts larger than 6, and they are abundant in the centers of local galaxies. Their formation mechanisms, however, a…
Electromagnetic signatures from accreting massive black hole binaries in time domain photometric surveys
Fabiola Cocchiararo, Alessia Franchini, Alessandro Lupi +1
We study spectral and time variability of accreting massive black hole binaries (MBHBs) at milli-pc separations surrounded by a geometrically thin circumbinary disc. We present the…
Emission signatures from sub-pc Post-Newtonian binaries embedded in circumbinary discs
Alessia Franchini, Matteo Bonetti, Alessandro Lupi +1
We study the dynamical evolution of quasi-circular equal mass massive black hole binaries embedded in circumbinary discs from separations of down to the merger,…
The importance of live binary evolution in numerical simulations of binaries embedded in circumbinary discs
Alessia Franchini, Alessandro Lupi, Alberto Sesana +1
The shrinking of a binary orbit driven by the interaction with a gaseous circumbinary disc, initially advocated as a potential way to catalyze the binary merger, has been recently…
Quasi-periodic eruptions from impacts between the secondary and a rigidly precessing accretion disc in an extreme mass-ratio inspiral system
Alessia Franchini, Matteo Bonetti, Alessandro Lupi +7
X-ray quasi-periodic eruptions (QPEs) represent a recently discovered example of extreme X-ray variability associated with supermassive black holes. These are high-amplitude bursts…
Optical follow-up of the tick-tock massive black hole binary candidate
Massimo Dotti, Matteo Bonetti, Fabio Rigamonti +8
The observation of a population of massive black hole binaries (MBHBs) is key for our complete understanding of galaxy mergers and for the characterization of the expected gravitat…
Resolving massive black hole binaries evolution via adaptive particle-splitting
Alessia Franchini, Alessandro Lupi, Alberto Sesana
The study of the interaction of a massive black hole binary with its gaseous environment is crucial in order to be able to predict merger rates and possible electromagnetic counter…
The fine line between total and partial tidal disruption events
Deborah Mainetti, Alessandro Lupi, Sergio Campana +4
Flares from tidal disruption events are unique tracers of quiescent black holes at the centre of galaxies. The appearance of these flares is very sensitive to whether the star is t…
Hydrodynamical simulations of the tidal stripping of binary stars by massive black holes
Deborah Mainetti, Alessandro Lupi, Sergio Campana +1
In a galactic nucleus, a star on a low angular momentum orbit around the central massive black hole can be fully or partially disrupted by the black hole tidal field, lighting up t…
