The Bardeen-Petterson effect in accreting supermassive black-hole binaries: disc breaking and critical obliquity
Rebecca Nealon, Enrico Ragusa, Davide Gerosa +2
The inspiral of supermassive black-hole binaries in gas-rich environment is driven by the presence of an accretion disc and viscous interactions tend to align the spin of the black…
Gravitational-wave population inference at past time infinity
Matthew Mould, Davide Gerosa
Population studies of stellar-mass black-hole binaries have become major players in gravitational-wave astronomy. The underlying assumptions are that the targeted source parameters…
Population-informed priors in gravitational-wave astronomy
Christopher J. Moore, Davide Gerosa
We describe a Bayesian formalism for analyzing individual gravitational-wave events in light of the rest of an observed population. This analysis reveals how the idea of a "populat…
Modeling the outcome of supernova explosions in binary population synthesis using the stellar compactness
Maciej Dabrowny, Nicola Giacobbo, Davide Gerosa
Following the collapse of their cores, some of the massive binary stars that populate our Universe are expected to form merging binaries composed of black holes and neutron stars.…
Bayesian parameter estimation of stellar-mass black-hole binaries with LISA
Riccardo Buscicchio, Antoine Klein, Elinore Roebber +4
We present a Bayesian parameter-estimation pipeline to measure the properties of inspiralling stellar-mass black hole binaries with LISA. Our strategy (i) is based on the coherent…
Looking for the parents of LIGO's black holes
Vishal Baibhav, Emanuele Berti, Davide Gerosa +2
Solutions to the two-body problem in general relativity allow us to predict the mass, spin and recoil velocity of a black-hole merger remnant given the masses and spins of its bina…
Hierarchical mergers of stellar-mass black holes and their gravitational-wave signatures
Davide Gerosa, Maya Fishbach
We review theoretical findings, astrophysical modeling, and current gravitational-wave evidence of hierarchical stellar-mass black-hole mergers. While most of the compact binary me…
High mass but low spin: an exclusion region to rule out hierarchical black-hole mergers as a mechanism to populate the pair-instability mass gap
Davide Gerosa, Nicola Giacobbo, Alberto Vecchio
The occurrence of pair-instability supernovae is predicted to prevent the formation of black holes with masses . Recent gravitational-wave detections in this ma…
Testing general relativity with gravitational-wave catalogs: the insidious nature of waveform systematics
Christopher J. Moore, Eliot Finch, Riccardo Buscicchio +1
Gravitational-wave observations of binary black holes allow new tests of general relativity to be performed on strong, dynamical gravitational fields. These tests require accurate…
A taxonomy of black-hole binary spin precession and nutation
Daria Gangardt, Nathan Steinle, Michael Kesden +2
Binary black holes with misaligned spins will generically induce both precession and nutation of the orbital angular momentum about the total angular momentum . Th…
Eccentric binary black hole surrogate models for the gravitational waveform and remnant properties: comparable mass, nonspinning case
Tousif Islam, Vijay Varma, Jackie Lodman +6
We develop new strategies to build numerical relativity surrogate models for eccentric binary black hole systems, which are expected to play an increasingly important role in curre…
