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…

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…

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…

Nanohertz Gravitational Wave Astronomy during the SKA Era: An InPTA perspective

Bhal Chandra Joshi, Achamveedu Gopakumar, Arul Pandian +34

Decades long monitoring of millisecond pulsars, which exhibit highly stable rotational periods, in pulsar timing array experiments is on the threshold of discovering nanohertz stoc…

Low-frequency wideband timing of InPTA pulsars observed with the uGMRT

K Nobleson, Nikita Agarwal, Raghav Girgaonkar +29

High-precision measurements of the pulsar dispersion measure (DM) are possible using telescopes with low-frequency wideband receivers. We present an initial study of the applicatio…

Evidence for profile changes in PSR J1713+0747 using the uGMRT

Jaikhomba Singha, Mayuresh P Surnis, Bhal Chandra Joshi +29

PSR J1713+0747 is one of the most precisely timed pulsars in the international pulsar timing array experiment. This pulsar showed an abrupt profile shape change between April 16, 2…
