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…

Spin precession effects in the phasing formula of eccentric compact binary inspirals up to the second post-Newtonian order
Soham Bhattacharyya, Omkar Sridhar
Compact binary systems emitting gravitational waves (GWs) can exhibit orbital eccentricity, along with generic spin orientations, leading to the precession of the orbital angular m…

Spin effects in the phasing formula of eccentric compact binary inspirals up to the third post-Newtonian order
Omkar Sridhar, Soham Bhattacharyya, Kaushik Paul +1
Compact binary sources that emit gravitational waves (GW) are expected to be both spinning and on eccentric orbits. No closed-form expression for the phasing of GWs are available t…
