A Search for X-ray/UV Correlation in the Reflection-Dominated Seyfert 1 Galaxy Mrk 1044
Samuzal Barua, Oluwashina K. Adegoke, Ranjeev Misra +3
Correlated variability between coronal X-rays and disc optical/UV photons provides a very useful diagnostic of the interplay between the different regions around an active galactic…
Investigating the Energy-Dependent Temporal Nature of Black Hole Binary System H 1743-322
Nazma Husain, Akash Garg, Ranjeev Misra +1
Black hole X-ray binaries routinely exhibit Quasi Periodic Oscillations (QPOs) in their Power density spectrum. Studies of QPOs have demonstrated immense ability to understand thes…
Black hole spin measurements in LMC X-1 and Cyg X-1 are highly model-dependent
Andrzej A. Zdziarski, Srimanta Banerjee, Swadesh Chand +4
The black-hole spin parameter, , was measured to be close to its maximum value of 1 in many accreting X-ray binaries. In particular, was found in a number of…
Probing the soft state evolution of 4U 1543-47 during its 2021 outburst using AstroSat
Nazma Husain, Yash Bhargava, Akash Garg +3
4U 1543-47 underwent its brightest outburst in 2021 after two decades of inactivity. During its decay phase, AstroSat conducted nine observations of the source spanning from July $…
Correlations between QPO frequencies and spectral parameters of GRS 1915+105 using AstroSat observations
Ruchika Dhaka, Ranjeev Misra, JS Yadav +1
In this work, we study the correlation between Quasi-periodic Oscillation (QPO) frequency and the spectral parameters during various X-ray states in the black hole binary GRS 1915+…
Broadband Spectral properties of MAXI J1348--630 using AstroSat Observations
Gitika Mall, Jithesh Vadakkumthani, Ranjeev Misra
We present broadband X-ray spectral analysis of the black hole X-ray binary MAXI J1348--630, performed using five AstroSat observations. The source was in the soft spectral state f…
