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…
Correlations Between kHz QPOs and Spectral Parameters from Time-Resolved Spectro-Temporal Analysis of 4U 1728-34
Kewal Anand, Ranjeev Misra, J. S. Yadav +1
We present a time-resolved analysis of the persistent emission in 4U 1728--34 using AstroSat observations from 2016 to 2019. We detect kilohertz quasi-periodic oscillations (kHz QP…
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…
Discovery of a new flaring class in GRS 1915+105 using AstroSat
Ruchika Dhaka, JS Yadav, Ranjeev Misra +1
Highly variable Black Hole X-ray Binary (BHXB) GRS~1915+105 has shown many flaring classes when the source oscillates between the High Soft state (HS) and the Hard Intermediate sta…
Exploring the broadband spectral and timing characteristics of GRS 1915+105 with AstroSat and NICER observations
Ruchika Dhaka, Ranjeev Misra, JS Yadav +1
In this study, we undertake a spectral-timing analysis of the black hole X-ray binary source GRS 1915+105 using simultaneous observations carried out by AstroSat (LAXPC and SXT) an…
Detection of simultaneous QPO triplets in 4U 1728-34 and constraining the neutron star mass and moment of inertia
Kewal Anand, Ranjeev Misra, J. S. Yadav +3
We report simultaneous detection of twin kHz and Hz quasi-periodic oscillations (QPOs) in the time-resolved analysis of the AstroSat/LAXPC observation of the neutron star…
