Establishing Compactness as a Population Observable in Gravitational-Wave Astronomy
Shrobana Ghosh, Charlie Hoy, Mark Hannam +1
Classically, black holes (BHs) are the most compact objects predicted in nature with C=0.5 in the Schwarzschild limit; C is defined as the mass-to-radius ratio in geometric units.…
Compactness Inference in Gravitational-Wave Mergers with PhenomDECO: Catalog Benchmarks and Robustness Diagnostics
Shrobana Ghosh, Charlie Hoy, Mark Hannam +1
Several gravitational wave (GW) observations have been identified as binary black hole (BBH) mergers, including systems with component masses that challenge typical formation scena…
PhenomXPNR: An improved gravitational wave model linking precessing inspirals and NR-calibrated merger-ringdown
Eleanor Hamilton, Marta Colleoni, Jonathan E. Thompson +10
We present the frequency-domain quasi-circular precessing binary-black-hole model PhenomXPNR. This model combines the most precise available post-Newtonian description of the evolu…
On the Identification of Exotic Compact Binaries with Gravitational Waves: a Phenomenological approach
Shrobana Ghosh, Mark Hannam
Gravitational wave (GW) astronomy has been hailed as a gateway to discovering unexpected phenomena in the universe. Over the last decade there have been close to one hundred GW obs…
Revisiting the relationship of black-hole kicks and multipole asymmetries
Jannik Mielke, Shrobana Ghosh, Angela Borchers +1
Precession in black-hole binaries is caused by a misalignment between the total spin and the orbital angular momentum. The gravitational-wave emission of such systems is anisotropi…
Observability of spin precession in the presence of a black-hole remnant kick
Angela Borchers, Frank Ohme, Jannik Mielke +1
Remnants of binary black-hole mergers can gain significant recoil or kick velocities when the binaries are asymmetric. The kick is the consequence of anisotropic emission of gravit…
