Probing modified gravitational-wave dispersion with bursts from eccentric black-hole binaries
Nicholas Loutrel, Ava Bailey, Davide Gerosa
Gravitational waves in general relativity are non-dispersive, yet a host of modified theories predict dispersion effects during propagation. In this work, we consider the impact of…
LHS in LHS: A new expansion strategy for Latin hypercube sampling in simulation design
Matteo Boschini, Davide Gerosa, Alessandro Crespi +1
Latin Hypercube Sampling (LHS) is a prominent tool in simulation design, with a variety of applications in high-dimensional and computationally expensive problems. LHS allows for v…
Coincident morphological transitions in precessing black-hole binaries
Davide Gerosa, Giulia Foroni, Giulia Fumagalli +1
We present new insights into the phenomenology of post-Newtonian spin precession in black-hole binaries. Using multi-timescale methods, previous work has shown that the precession…
PRECESSION 2.1: black-hole binary spin precession on eccentric orbits
Giulia Fumagalli, Davide Gerosa, Nicholas Loutrel
We present version 2.1 of the public code {\sc precession}, a Python module for studying the post-Newtonian dynamics of precessing black hole binaries. In this release, we extend t…
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…
Scalable data-analysis framework for long-duration gravitational waves from compact binaries using short Fourier transforms
Rodrigo Tenorio, Davide Gerosa
We introduce a framework based on short Fourier transforms (SFTs) to analyze long-duration gravitational wave signals from compact binaries. Targeted systems include binary neutron…
Non-adiabatic dynamics of eccentric black-hole binaries in post-Newtonian theory
Giulia Fumagalli, Nicholas Loutrel, Davide Gerosa +1
Eccentric black-hole binaries are among the most awaited sources of gravitational waves, yet their dynamics lack a consistent framework that provides a detailed and physically robu…
Orbital eccentricity in general relativity from catastrophe theory
Matteo Boschini, Nicholas Loutrel, Davide Gerosa +1
While the orbital eccentricity is a key feature of the gravitational two-body problem, providing an unambiguous definition in general relativity poses significant challenges. Despi…
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…
