Can GW231123 have a stellar origin?
Djuna Croon, Davide Gerosa, Jeremy Sakstein
The gravitational wave event GW231123 detected by the LIGO interferometers during their fourth observing run features two black holes with source-frame masses of $137^{+23}_{-18} M…
GW200208_222617 as an eccentric black-hole binary merger: properties and astrophysical implications
Isobel Romero-Shaw, Jakob Stegmann, Hiromichi Tagawa +4
Detecting orbital eccentricity in a stellar-mass black-hole merger would point to a non-isolated formation channel. Eccentric binaries can form in dense stellar environments such a…
Distinguishing the Origin of Eccentric Black Hole Mergers with Gravitational-wave Spin Measurements
Jakob Stegmann, Davide Gerosa, Isobel Romero-Shaw +3
It remains an open question whether the binary black hole mergers observed with gravitational-wave detectors originate from the evolution of isolated massive binary stars or were d…
Minimum gas mass accreted by spinning intermediate-mass black holes in stellar clusters
Konstantinos Kritos, Luca Reali, Davide Gerosa +1
The spin of intermediate-mass black holes (IMBHs) growing through repeated black hole mergers in stellar clusters statistically asymptotes to zero. Putative observations of IMBHs w…
Residual eccentricity as a systematic uncertainty on the formation channels of binary black holes
Giulia Fumagalli, Isobel Romero-Shaw, Davide Gerosa +3
Resolving the formation channel(s) of merging binary black holes is a key goal in gravitational-wave astronomy. The orbital eccentricity is believed to be a precious tracer of the…
Probing AGN jet precession with LISA
Nathan Steinle, Davide Gerosa, Martin G. H. Krause
The precession of astrophysical jets produced by active-galactic nuclei is likely related to the dynamics of the accretion disks surrounding the central supermassive black holes (B…
pAGN: the one-stop solution for AGN disc modeling
Daria Gangardt, Alessandro Alberto Trani, Clément Bonnerot +1
Models of accretion discs surrounding active galactic nuclei (AGNs) find vast applications in high-energy astrophysics. The broad strategy is to parametrize some of the key disc pr…
