Revisiting wideband pulsar timing measurements
Abhimanyu Susobhanan, Avinash Kumar Paladi, Réka Desmecht +28
In the wideband paradigm of pulsar timing, the time of arrival of a pulsar pulse is measured simultaneously with the corresponding dispersion measure from a frequency-resolved inte…
Post-glitch Recovery and the Neutron Star Structure: The Vela Pulsar
Himanshu Grover, Erbil GügercinoÄlu, Bhal Chandra Joshi +4
We present a detailed analysis of the Vela pulsar's rotational behaviour using approximately 100 months of observational data spanning from September 2016 to January 2025, during w…
Anomalous scattering of pulsars towards the Gum Nebula
M. A. Krishnakumar, Bhal Chandra Joshi, P. K. Manoharan
We report wideband scatter-broadening estimates of 14 pulsars towards the Gum nebula region using the Band-3 of the upgraded GMRT. This work increases the measurements of frequency…
The Indian Pulsar Timing Array Data Release 2: I. Dataset and Timing Analysis
Prerna Rana, Pratik Tarafdar, Nobleson K +44
The Indian Pulsar Timing Array (InPTA) employs unique features of the upgraded Giant Metrewave Radio Telescope (uGMRT) to monitor dozens of the International Pulsar Timing Array (I…
The ORT and the uGMRT Pulsar Monitoring Program : Pulsar Timing Irregularities & the Gaussian Process Realization
Himanshu Grover, Bhal Chandra Joshi, Jaikhomba Singha +8
The spin-down law of pulsars is generally perturbed by two types of timing irregularities: glitches and timing noise. Glitches are sudden changes in the rotational frequency of pul…
