Super-Eddington accretion in protogalactic cores
Tommaso Zana, Pedro R. Capelo, Mairo Boresta +6
The presence of massive black holes (BHs) exceeding already at redshift challenges standard models of BH growth. Super-Eddington (SE) accretion has…
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…
Fast pre-merger detection of massive black-hole binaries in LISA based on time-frequency excess power
Francesco Nobili, Malvina Bellotti, Riccardo Buscicchio +2
The Laser Interferometer Space Antenna is expected to observe gravitational waves from massive black hole binaries across cosmic time. Many are anticipated to be detectable hours t…
A novel sub-grid model for super-Eddington accretion of spinning black holes in galaxy-scale simulations
Wei-Bo Kao, Pedro R. Capelo, Elia Cenci +3
Super-Eddington accretion has been proposed to explain the existence of black holes (BHs) with masses exceeding a billion solar masses within the first billion years after the Big…
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…
