Multibanded Reduced Order Quadrature Techniques for Gravitational Wave Inference
Murdoc Newell, Alexis Boudon, Hong Qi
Reduced-order quadrature (ROQ) is commonly used to accelerate parameter estimation in gravitational wave astronomy; however, constructing ROQ bases can be computationally costly, p…
GW231123: a Binary Black Hole Merger with Total Mass 190-265
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1771
On 2023 November 23 the two LIGO observatories both detected GW231123, a gravitational-wave signal consistent with the merger of two black holes with masses $137^{+23}_{-18}\, M_\o…
A Realistic Projection for Constraining Neutron Star Equation of State with the LIGO-Virgo-KAGRA Detector Network in the A+ Era
Alexis Boudon, Hong Qi, Jean-François Coupechoux +2
The LIGO-Virgo-KAGRA network in the upcoming A+ era with upgrades of both Advanced LIGO and Advanced Virgo will enable more frequent and precise observations of binary neutron star…
Supersonic friction of a black hole traversing a self-interacting scalar dark matter cloud
Alexis Boudon, Philippe Brax, Patrick Valageas
Black Holes (BH) traversing a dark matter cloud made out of a self-interacting scalar soliton are slowed down by two complementary effects. At low subsonic speeds, the BH accretes…
Gravitational waves from binary black holes in a self-interacting scalar dark matter cloud
Alexis Boudon, Philippe Brax, Patrick Valageas +1
We investigate the imprints of accretion and dynamical friction on the gravitational-wave signals emitted by binary black holes embedded in a scalar dark matter cloud. As a key fea…
Subsonic accretion and dynamical friction for a black hole moving through a self-interacting scalar dark matter cloud
Alexis Boudon, Philippe Brax, Patrick Valageas
We investigate the flow around a black hole moving through a cloud of self-interacting scalar dark matter. We focus on the large scalar mass limit, with quartic self-interactions,…
Baryogenesis through Asymmetric Hawking Radiation from Primordial Black Holes as Dark Matter
Alexis Boudon, Benjamin Bose, Hyat Huang +1
We examine the extent to which primordial black holes (PBHs) can constitute the observed dark matter while also giving rise to the measured matter-antimatter asymmetry and account…
