Population-level correlations in Bayesian statistics: an illustrative model for gravitational-wave astronomy
Caroline B. Owen, Alexandre Toubiana, Davide Gerosa
With increasingly large numbers of gravitational-wave events, population inference is now beginning to move beyond predictions of marginal distributions and to probe correlations b…
A framework for LISA population inference
Alexandre Toubiana, Jonathan Gair
The Laser Interferometer Space Antenna (LISA) is expected to have a source rich data stream containing signals from large numbers of many different types of source. This will inclu…
Gravitational-Wave Background from Extragalactic Double White Dwarfs for LISA
Guillaume Boileau, Tristan Bruel, Alexandre Toubiana +2
Recent studies have revealed the contribution of extragalactic DWD to the astrophysical SGWB could be detectable in the mHz regime by LISA. Conversely, the presence of this SGWB co…
Comparing astrophysical models to gravitational-wave data in the observable space
Alexandre Toubiana, Davide Gerosa, Matthew Mould +9
Comparing population-synthesis models to the results of hierarchical Bayesian inference in gravitational-wave astronomy requires a careful understanding of the domain of validity o…
Trust the process: mapping data-driven reconstructions to informed models using stochastic processes
Stefano Rinaldi, Alexandre Toubiana, Jonathan R. Gair
Gravitational-wave astronomy has entered a regime where it can extract information about the population properties of the observed binary black holes. The steep increase in the num…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +65
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
A pipeline for searching and fitting instrumental glitches in LISA data
Martina Muratore, Jonathan Gair, Olaf Hartwig +2
Instrumental artefacts, such as glitches, can significantly compromise the scientific output of LISA. Our methodology employs advanced Bayesian techniques, including Reversible Jum…
Systematic Biases in Estimating the Properties of Black Holes Due to Inaccurate Gravitational-Wave Models
Arnab Dhani, Sebastian H. Völkel, Alessandra Buonanno +5
Gravitational-wave (GW) observations of binary black-hole (BBH) coalescences are expected to address outstanding questions in astrophysics, cosmology, and fundamental physics. Real…
Indistinguishability criterion and estimating the presence of biases
Alexandre Toubiana, Jonathan R. Gair
In these notes, we comment on the standard indistinguishability criterion often used in the gravitational wave community to set accuracy requirements on waveforms. Revisiting the h…
Gravitational wave populations and cosmology with neural posterior estimation
Konstantin Leyde, Stephen R. Green, Alexandre Toubiana +1
We apply neural posterior estimation for fast-and-accurate hierarchical Bayesian inference of gravitational wave populations. We use a normalizing flow to estimate directly the pop…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
Measuring source properties and quasi-normal-mode frequencies of heavy massive black-hole binaries with LISA
Alexandre Toubiana, Lorenzo Pompili, Alessandra Buonanno +2
The laser-interferometer space antenna (LISA) will be launched in the mid 2030s. It promises to observe the coalescence of massive black-hole (BH) binaries with signal-to-noise rat…
Is there an excess of black holes around ? Optimising the complexity of population models with the use of reversible jump MCMC
Alexandre Toubiana, Michael L. Katz, Jonathan R. Gair
Some analyses of the third gravitational wave catalogue released by the LIGO-Virgo-KAGRA collaboration (LVK) suggest an excess of black holes around . In order to…
Detectability and parameter estimation of GWTC-3 events with LISA
Alexandre Toubiana, Stanislav Babak, Sylvain Marsat +1

Binaries of relatively massive black holes like GW190521 have been proposed to form in dense gas environments, such as the disks of Active Galactic Nuclei (AGNs), and they might be…
Discriminating between different scenarios for the formation and evolution of massive black holes with LISA
Alexandre Toubiana, Kaze W. K. Wong, Stanislav Babak +5
Electromagnetic observations have provided strong evidence for the existence of massive black holes in the center of galaxies, but their origin is still poorly known. Different sce…
