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…

Investigating the disappearance of a type-C QPO in black hole X-ray binary Swift J151857-572147 with AstroSat

Biki Ram, Manoneeta Chakraborty, Mayukh Pahari

We present a timing and broadband spectral study of the AstroSat observation of the black hole low mass X-ray binary Swift J151857.0--572147, focusing on its evolution across two t…

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…

Understanding corona and disk evolution in black hole X-ray binaries through a comprehensive study of their broadband variability and QPO characteristics

Biki Ram, Manoneeta Chakraborty

The shape of the power spectrum of the black hole low-mass X-ray binary evolves systematically over different spectral states during an outburst. Therefore, the power colours (rati…

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…
