Recovering Intrinsic Pulsar Profiles and Scattering Parameters with a CLEAN-Based Algorithm for High-Precision Timing
Adarsh Bathula, M. A. Krishnakumar, S. Jena
In high precision pulsar timing, the accurate recovery of intrinsic pulsar profiles and their associated scattering parameters is of paramount importance. In this paper, we present…

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…
