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…

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…

Post-glitch Recovery and the Neutron Star Structure: The Vela Pulsar

Himanshu Grover, Erbil Gügercinoğlu, 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…

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…

Low-frequency pulse-jitter measurement with the uGMRT I : PSR J04374715

Tomonosuke Kikunaga, Shinnosuke Hisano, Neelam Dhanda Batra +22

High-precision pulsar timing observations are limited in their accuracy by the jitter noise that appears in the arrival time of pulses. Therefore, it is important to systematically…
