Probing the QPO and spectro-temporal evolution of MAXI J1750-327 with XPoSat during its first detected outburst : Constraints on black-hole mass and spin
Meghamani Haldar, Biki Ram, Shubhrangshu Ghosh +3
We present a comprehensive timing and broadband spectral study of the newly discovered black hole low-mass X-ray binary candidate MAXI J1750-327 during its August 2026 outburst, us…
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…
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…
Spectro-temporal investigation of the black hole X-ray transient 4U 1543-475 during the 2021 outburst
Biki Ram, Manoneeta Chakraborty, Unnati Kashyap
We report a detailed spectro-temporal analysis of the black hole (BH) low mass X-ray binary (LMXB) 4U 1543-475 during its 2021 outburst using the data from LAXPC (Large Area X-ray…
Broadband spectro-temporal investigation of neutron star low-mass X-ray binary GX 349+2
Unnati Kashyap, Manoneeta Chakraborty, Sudip Bhattacharyya +1
We report a broadband investigation of the Z-type neutron star (NS) low mass X-ray binary (LMXB) GX 349+2 using AstroSat and NICER. AstroSat observed the source exhibiting large sc…
Broadband time-resolved spectroscopy of thermonuclear X-ray bursts from 4U 1636-536 using AstroSat
Unnati Kashyap, Biki Ram, Tolga Guver +1
Broadband spectral studies of Type-I X-ray bursts can put strong constraints on the physics of burst spectra as well as their interaction with the environment. We present the resul…
