Exploring the AGN Accretion Disks using Continuum Reverberation Mapping
Vivek Kumar Jha, Ravi Joshi, Jayesh Saraswat +3
In the innermost regions of Active Galactic Nuclei (AGN), matter is understood to be flowing onto the Supermassive black hole (SMBH), which forms an accretion disk. This disk is re…
Spectral index variation across X-shaped radio galaxies
Dusmanta Patra, Ravi Joshi, Gopal-Krishna
The formation mechanism of the enigmatic subclass of radio galaxies, called 'X-shaped radio galaxies' (XRGs), or 'winged' radio galaxies, which account for of the radio…
Intranight Optical Variability of Blazars and Radio-quiet Quasars using the ZTF Survey
Vibhore Negi, Gopal-Krishna, Ravi Joshi +4
We explore the potential of the ongoing Zwicky-Transient-Facility (ZTF) survey for studying Intra-Night Optical Variability (INOV) of active galactic nuclei (AGN), in particular fo…
A physically-motivated perspective of the Fanaroff-Riley classification of radio galaxies
Gopal-Krishna, Paul J. Wiita, Ravi Joshi +1
A small subset of extragalactic double radio sources, termed HYMORS (HYbrid MOrpholgy Radio Sources), is distinguished by a very unusual, hybrid morphology in terms of the Fanaroff…
Evidence of under-developed torus and broad-line region of weak emission line quasars based on their spectral energy distribution
Ritish Kumar, Hum Chand, Ravi Joshi
To unravel the dominant cause of the weak emission line in a subset of optically selected radio-quiet 'weak emission line quasars' (WLQs), we have investigated the possibility of a…
The X-shaped radio galaxy J0725+5835 is associated with an AGN pair
Xiaolong Yang, Jialu Ji, Ravi Joshi +6
X-shaped radio galaxies (XRGs) are those that exhibit two pairs of unaligned radio lobes (main radio lobes and "wings"), one of the promising models for the peculiar morphology is…
