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…

Spectropolarimetric study of 4U 163047 in Steep Power law state with IXPE and NICER

Divya Rawat, Akash Garg, Mariano Méndez

We probe the spectropolarimetric properties of the black-hole binary source 4U 163047 in the steep power law state. We detect a significant polarization fraction of 7 % at…

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 $…

Flux-resolved Spectropolarimetric Evolution of the X-Ray Pulsar Hercules X-1 Using IXPE

Akash Garg, Divya Rawat, Yash Bhargava +2

We conduct a spectro-polarimetric study of the accreting X-ray pulsar Hercules X-1 using observations with the Imaging X-ray Polarimetry Explorer (IXPE). IXPE monitored the source…

Detection of X-ray polarized emission and accretion-disk winds with IXPE and NICER in the black-hole X-ray binary 4U 1630-47

Divya Rawat, Akash Garg, Mariano Méndez

We detect a high level of polarization in the X-ray emission of the black-hole binary 4U 1630-47 in an observation with the Imaging X-ray Polarimetry Explorer. The 2-8 keV polariza…

On the energy dependence of the QPO phenomenon in the black hole system MAXI J1535-571

Akash Garg, Ranjeev Misra, Somasri Sen

Previous analysis of AstroSat observations of the black hole system MAXI J1535-571, have revealed the presence of a strong Quasi-Periodic Oscillation (QPO) whose frequency is corre…

Identifying the radiative components responsible for Quasi-Periodic Oscillations of black hole systems

Akash Garg, Ranjeev Misra, Somasri Sen

While the dynamical origin of the variability observed in Galactic Black hole systems, such as quasi-periodic oscillations (QPOs), are still a matter of debate, insight into the ra…
