A Collapsar-Disk Origin for GW190814
Vishal Baibhav, Brian D. Metzger, Lam Hui
GW190814 was a remarkable gravitational-wave (GW) event: a merger between a 23 solar-mass black hole (BH) and a 2.6 solar-mass compact object, with an extreme mass ratio that is di…
Inferring Eccentricity of Binary Black Holes from Spin-Orbit Misalignment
Vishal Baibhav
Orbital eccentricity remains one of the least accessible parameters in observations of binary black hole (BBH) systems, largely erased by gravitational radiation long before detect…
Pulsar Rockets and Gaia Neutron Star Binaries
Vishal Baibhav, Andrei Gruzinov, Yuri Levin
We prove that the spin-aligned electromagnetic recoil force acting on a pulsar vanishes identically in Force-Free Electrodynamics. This contrasts with Hirai et al.'s recent argumen…
Revising the Spin and Kick Connection in Isolated Binary Black Holes
Vishal Baibhav, Vicky Kalogera
The origin of black hole (BH) spins remains one of the least understood aspects of BHs. Despite many uncertainties, it is commonly assumed that if BHs originated from isolated mass…
Dropping Anchor: Understanding the Populations of Binary Black Holes with Random and Aligned Spin Orientations
Vishal Baibhav, Zoheyr Doctor, Vicky Kalogera
The relative spin orientations of black holes (BHs) in binaries encode their evolutionary history: BHs assembled dynamically should have isotropically distributed spins, while spin…
Dynamical formation of black hole binaries in dense star clusters: Rapid cluster evolution code
Konstantinos Kritos, Vladimir Strokov, Vishal Baibhav +1
Gravitational-wave observations have just started probing the properties of black hole binary merger populations. The observation of binaries with very massive black holes and sign…
The role of supernova convection for the lower mass gap in the isolated binary formation of gravitational wave sources
Aleksandra Olejak, Chris L. Fryer, Krzysztof Belczynski +1
Understanding astrophysical phenomena involving compact objects requires an insight about the engine behind core-collapse supernovae (SNe) and the fate of the stellar collapse of m…
The mass gap, the spin gap, and the origin of merging binary black holes
Vishal Baibhav, Davide Gerosa, Emanuele Berti +3
Two of the dominant channels to produce the black-hole binary mergers observed by LIGO and Virgo are believed to be the isolated evolution of stellar binaries in the field and dyna…
Probing the Nature of Black Holes: Deep in the mHz Gravitational-Wave Sky
Vishal Baibhav, Leor Barack, Emanuele Berti +26
Black holes are unique among astrophysical sources: they are the simplest macroscopic objects in the Universe, and they are extraordinary in terms of their ability to convert energ…
Constraining the fraction of binary black holes formed in isolation and young star clusters with gravitational-wave data
Yann Bouffanais, Michela Mapelli, Davide Gerosa +4
Ten binary black-hole mergers have already been detected during the first two observing runs of advanced LIGO and Virgo, and many more are expected to be observed in the near futur…
Binary radial velocity measurements with space-based gravitational-wave detectors
Kaze W. K. Wong, Vishal Baibhav, Emanuele Berti
Unlike traditional electromagnetic measurements, gravitational-wave observations are not affected by crowding and extinction. For this reason, compact object binaries orbiting arou…
