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…
Newly born extragalactic millisecond pulsars as efficient emitters of PeV neutrinos
Rajat K. Dey, Animesh Basak, Sabyasachi Ray +1
The origins of the diffuse flux of cosmogenic PeV neutrinos detected in the IceCube experiment during 2010 - 2017 remain unidentified. A population of extragalactic newly born fast…
Spectral lags of flaring events in 303 from RXTE Observations
Tamal Sarkar, Samir K Sarkar, Arunava Bhadra
This work reports the first discovery of (negative) spectral lags in the X-ray emission below 10 keV from the gamma ray binary 303 during large flaring episodes usin…
Newtonian analogue of corresponding spacetime dynamics of rotating black holes: Implication on black hole accretion
Shubhrangshu Ghosh, Tamal Sarkar, Arunava Bhadra
Based on the conserved Hamiltonian for a test particle, we have formulated a Newtonian analogue of Kerr spacetime in the `low energy limit of the test particle motion' that, in pri…
