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…

A Hidden Pulse: Uncovering a New Timing Signal in Cygnus X-1 with AstroSat

Sandeep K. Rout, Federico Garcia, Mariano Mendez +4

The study of fast variability properties in X-ray binaries advances our understanding of the physical processes and geometric properties of the accretion flow around the compact ob…

Disk reflection and energetics from the accreting millisecond pulsar SRGA J144459.2-604207

Christian Malacaria, Alessandro Papitto, Sergio Campana +11

Accreting millisecond pulsars (AMSPs) are excellent laboratories to study reflection spectra and their features from an accretion disk truncated by a rapidly rotating magnetosphere…

Spectro-polarimetry of GRB 180427A: evidence for distinct emission sites with varying polarisation

Rushikesh Sonawane, Shabnam Iyyani, Soumya Gupta +5

The dynamics of the origin of gamma-ray emissions in gamma-ray bursts (GRBs) remains an enigma. Through a joint analysis of GRB 180427A, observed by the Fermi Gamma-ray Space Teles…
