The spin magnitude of stellar-mass binary black holes evolves with the mass: evidence from gravitational wave data
Grégoire Pierra, Simone Mastrogiovanni, Stéphane Perriès
The relation between the mass and spin of stellar-mass binary black holes (BBHs) has been proposed to be a smoking gun for the presence of multiple formation channels for compact o…

Gravitational Wave Cosmology: Be Careful of the Black Hole Mass Spectrum
Grégoire Pierra
Gravitational waves (GWs) from compact binary coalescences (CBCs) offer insights into the universe expansion. The spectral siren method, used without electromagnetic counterparts (…
