Complex Energy-Dependent Behaviour of Quasi-Periodic Oscillation Observed in GRS 1915+105

Vaibhav Sharma, Ranjeev Misra, V. Jithesh +5

We present complex energy-resolved properties of quasi-periodic oscillations (QPOs) in the black hole X-ray binary GRS 1915+105 using an observation from the LAXPC instrument onboa…

Constraining Spin and Inclination Angle of XTE J2012+381 using AstroSat and NICER

Vaibhav Sharma, Ranjeev Misra, Shivani Chaudhary +2

We present a spectral analysis of a black hole X-ray binary XTE J2012+381 during its 2022 outburst, using data from NICER and AstroSat. Combining data from NICER, LAXPC20, and SXT,…

Evolution of the 2021 Outburst of GX 339-4 with AstroSat

Vaibhav Sharma, Ranjeev Misra, J S Yadav +2

We present a comprehensive study of the 2021 outburst of GX 339-4 using AstroSat observations in the hard-intermediate (HIMS) and soft-intermediate states (SIMS). Spectral and timi…
