Study of pulse jitter characteristics of PSR J1744-1134: Towards high precision pulsar timing with InPTA
Jibin Jose, Manoneeta Chakraborty, Neelam Dhanda Batra +15
Variations in the shapes of individual pulses introduce a broadband noise component in pulsar times of arrival beyond what is expected from radiometer noise, referred to as the jit…
Profile Reconstruction from Temporally Stable Emission Components for Timing PSR J1713+0747
Shaswata Chowdhury, M. A. Krishnakumar, Sharika Dhakappa +26
The assumption of long-term pulse-profile stability underpins high-precision pulsar timing and forms the basis of pulsar timing array experiments. However, several millisecond puls…
The Indian Pulsar Timing Array Data Release 2: III. Search for a Stochastic Gravitational Wave Background
Hemanga Tahbildar, Kunjal Vara, Mayuresh Surnis +28
We present the first independent search for an isotropic stochastic gravitational wave background in the second data release of the Indian Pulsar Timing Array, comprising of 27 mil…
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…
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…
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…
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…
High Precision Measurements of Interstellar Dispersion Measure with the upgraded GMRT
M. A. Krishnakumar, P. K. Manoharan, Bhal Chandra Joshi +19
Pulsar radio emission undergoes dispersion due to the presence of free electrons in the interstellar medium (ISM). The dispersive delay in the arrival time of pulsar signal changes…
Properties of rapidly rotating hot neutron stars with antikaon condensates at constant entropy per baryon
Neelam Dhanda Batra, Krishna Prakash Nunna, Sarmistha Banik
We consider a neutrino-free hot neutron star that contains antikaon condensates in its core and is at finite entropy per baryon. We find the equation of state for a range of entrop…
The Metallicities of the Broad Emission Line Regions in the Nitrogen-Loudest Quasars
Neelam Dhanda Batra, Jack A. Baldwin
We measured the metallicity Z in the broad emission line regions (BELRs) of 43 SDSS quasars with the strongest N IV] and N III] emission lines. These N-Loud QSOs have unusually low…
