The Indian Pulsar Timing Array Data Release 2: II. Customised Single-Pulsar Noise Analysis and Noise Budget
K. Nobleson, Churchil Dwivedi, Shantanu Desai +33
We present the results of customised single-pulsar noise analysis of 27 millisecond pulsars from the second data release of the Indian Pulsar Timing Array (InPTA-DR2). We model var…
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…
Combining the second data release of the European Pulsar Timing Array with low-frequency pulsar data
F. Iraci, A. Chalumeau, C. Tiburzi +46
Low-frequency radio data improve the sensitivity of pulsar timing arrays (PTAs) to propagation effects such as dispersion measure (DM) variations, enabling better noise characteriz…
Effects of Coronal Mass Ejection on PSR J1022+1001 and Possible Mode Change of PSR J2145-0750 in the InPTA DR2
Shaswata Chowdhury, M. A. Krishnakumar, Manjari Bagchi +27
The Indian Pulsar Timing Array (InPTA) has recently published its second data release (DR2), comprising the timing analysis of seven years of data on 27 millisecond pulsars (MSPs),…
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…
