On coordinate frames relevant for pulsar physics
Jyotijwal Debnath, Manjari Bagchi
Pulsars can be either isolated or binary (or even in triple) systems. Observational features of pulsars are used to probe various aspects of fundamental physics, including emission…
Profile Reconstruction from Temporally Stable Emission Components for Timing PSR J1713+0747
Shaswata Chowdhury, M. A. Krishnakumar, Sharika Dhakappa +26
The assumption of long-term pulse-profile stability underpins high-precision pulsar timing and forms the basis of pulsar timing array experiments. However, several millisecond puls…
On the effect of the light bending phenomenon for a pulsar in a binary with a Kerr black hole
Jyotijwal Debnath, Manjari Bagchi
We study the effect of light-bending on the signal of a pulsar in binaries with rotating black hole companions, focusing on stellar mass black holes. We show that the impacts of va…
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…
