A Hydrodynamical Thermal Irradiated Wind from the Outer Thin Accretion Disk in Low-luminosity Active Galactic Nuclei
Nagendra Kumar
Evidently, low-luminosity active galactic nuclei (LLAGNs) are comprised of an inner advective disk and an outer geometrically thin disk. Wind is inevitable in LLAGNs, mainly interp…
Plane Polarization in Comptonization process : a Monte Carlo study
Nagendra Kumar
High energies emissions observed in X-ray binaries (XRBs), active galactic nuclei (AGNs) are linearly polarized. The prominent mechanism for X-ray is the Comptonization process. We…
Probable low-frequency quasi-periodic oscillations in blazars from the ZTF survey
Anuvab Banerjee, Vibhore Negi, Ravi Joshi +6
We investigate the possible presence of quasi-periodic oscillation (QPO) signals in 2103 blazars from the Zwicky Transient Facility (ZTF) time-domain survey. We detect a low-freque…
Thermal irradiation induced wind outflow in a geometrically thin accretion disk: A hydrodynamic study
Nagendra Kumar, Banibrata Mukhopadhyay
Many astrophysical sources, e.g., cataclysmic variables, X-ray binaries, active galactic nuclei, exhibit a wind outflow, when they reveal a multicolor blackbody spectrum, hence har…
Blazars SED in Conical Plasma Flow : a Monte Carlo study
Nagendra Kumar, Pankaj Kushwaha
Blazars host the most powerful persistent relativistic conical jet -- a highly collimated anisotropic flow of material/plasma. Motivated by this, we explore the blazar's broadband…
High energy power-law tail in X-ray binaries and bulk Comptonization due to a outflow from a disk
Nagendra Kumar
We study the high energy power-law tail emission of X-ray binaries (XRBs) by a bulk Comptonization process which usually observe in the very high soft VHS state of blackhole BH XRB…
