Transformers with Physics-Informed Encodings and Simulation-Based Inference for Robust Detection of Eccentric Binary Black Holes in Pulsar Timing Array Data
Subhajit Dandapat, Alvin J. K. Chua
Pulsar timing arrays (PTAs) provide a unique window into nanohertz gravitational waves (GWs), but extracting astrophysical parameters from noisy, long-baseline timing residuals rem…

Improving DM estimates using low-frequency scattering-broadening estimates
Jaikhomba Singha, Bhal Chandra Joshi, M. A. Krishnakumar +28
A pulsar's pulse profile gets broadened at low frequencies due to dispersion along the line of sight or due to multi-path propagation. The dynamic nature of the interstellar medium…
