Uncovering the Physical Origins of Black Holes in the Milky Way for Astronomical Surveys
Ilia Kiato, Pierson Lipschultz, Vicky Kalogera +5
The observational landscape of stellar-mass black holes (BHs) in the Milky Way is expanding beyond X-ray binaries, with Gaia DR4 and Roman expected to open new windows onto BH popu…
The Mass-Ratio Distribution of the Low-Mass Binary Black Hole Subpopulation: A Natural Outcome of Isolated Binary Evolution
Monica Gallegos-Garcia, Anarya Ray, Vicky Kalogera +7
The observed merging binary black hole population is increasingly consistent with being composed of a mixture of subpopulations, each likely the result of different formation mecha…
On the Astrophysical Origin of Binary Black Hole Subpopulations: A Tale of Three Channels?
Anarya Ray, Shirsha Mukherjee, Michael Zevin +1
There is increasing evidence for multiple binary black hole~(BBH) subpopulations in the cumulative gravitational wave catalog by the LIGO-Virgo-KAGRA Collaboration. The astrophysic…
Characterizing Binary Black Hole Subpopulations in GWTC-4 with Binned Gaussian Processes: On the Origins of the Peak
Omkar Sridhar, Anarya Ray, Vicky Kalogera
Understanding the astrophysical origins of binary black holes requires accurate and flexible modeling of multi-dimensional population properties. In this \textit{Letter}, using a d…
Reexamining Evidence of a Pair-Instability Mass Gap in the Binary Black Hole Population
Anarya Ray, Vicky Kalogera
The fourth gravitational wave transient catalog~(GWTC-4) has enabled empirical probes of the theorized pair-instability gap in the higher end of the binary black hole~(BBH) mass-sp…
Hiding Out at the Low End: No Gap and a Peak in the Black-Hole Mass Spectrum
Anarya Ray, Will Farr, Vicky Kalogera
In recent years, the existence of a gap in the mass spectrum of compact objects formed from stellar collapse, between the heaviest neutron stars and the lightest black holes, has b…
