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…
Modelling the Future of Gaia Neutron Star-Main Sequence Binaries: From Eccentric Orbits to Millisecond Pulsar-White Dwarfs
Debatri Chattopadhyay, Kyle A. Rocha, Seth Gossage +3
We model the evolution of 21 Gaia neutron star (NS)-main-sequence binaries (orbital period -- days, eccentricity ) using binary evolutio…
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…
Forming Double Neutron Stars using Detailed Binary Evolution Models with POSYDON: Comparison to the Galactic Systems
Abhishek Chattaraj, Jeff J. Andrews, Simone S. Bavera +14
With over two dozen detections in the Milky Way, double neutron stars (DNSs) provide a unique window into massive binary evolution. We use the POSYDON binary population synthesis c…
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…
Structure and Skewness of the Effective Inspiral Spin Distribution of Binary Black Hole Mergers
Sharan Banagiri, Thomas A. Callister, Christian Adamcewicz +2
The detection of gravitational waves has brought to light a population of binary black holes that merge within a Hubble time. Multiple formation channels can contribute to this pop…
