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…
