Precision of localization of single gravitational-wave source with pulsar timing array
Ryo Kato, Keitaro Takahashi
Pulsar Timing Arrays (PTAs) are expected to be able to detect gravitational waves (GWs) from individual supermassive black hole binaries in the near future. In order to identify th…
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…
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…
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…
Search for ultralight scalar dark matter with NANOGrav pulsar timing arrays
Ryo Kato, Jiro Soda
An ultralight scalar field is a candidate for the dark matter. The ultralight scalar dark matter with mass around induces oscillations of the pulse arrival tim…
Probing circular polarization in stochastic gravitational wave background with pulsar timing arrays
Ryo Kato, Jiro Soda
We study the detectability of circular polarization in a stochastic gravitational wave background from various sources such as supermassive black hole binaries, cosmic strings, and…
