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…
Gravitational physics in the context of Indian astronomy: A vision document
P. Ajith, K. G. Arun, Sukanta Bose +13
Contributions from the Indian gravity community have played a significant role in shaping several branches of astronomy and astrophysics. This document reviews some of the most imp…
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…
Multi-band Extension of the Wideband Timing Technique
Avinash Kumar Paladi, Churchil Dwivedi, Prerna Rana +27
The wideband timing technique enables the high-precision simultaneous estimation of pulsar Times of Arrival (ToAs) and Dispersion Measures (DMs) while effectively modeling frequenc…
The Indian Pulsar Timing Array: First data release
Pratik Tarafdar, Nobleson K., Prerna Rana +35
We present the pulse arrival times and high-precision dispersion measure estimates for 14 millisecond pulsars observed simultaneously in the 300-500 MHz and 1260-1460 MHz frequency…
pinta: The uGMRT Data Processing Pipeline for the Indian Pulsar Timing Array
Abhimanyu Susobhanan, Yogesh Maan, Bhal Chandra Joshi +20
We introduce pinta, a pipeline for reducing the upgraded Giant Metre-wave Radio Telescope (uGMRT) raw pulsar timing data, developed for the Indian Pulsar Timing Array experiment. W…
