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…
Radio activity of supermassive black holes with extremely high accretion rates
Xiaolong Yang, Su Yao, Jun Yang +8
Radio emission from the high- and super-Eddington accreting active galactic nuclei (AGNs) has various origins: a persistent jet, the magnetized corona and the wind-like outflows. I…
A unified framework for X-shaped radio galaxies
David Garofalo, Ravi Joshi, Xiaolong Yang +3
We propose a radically different picture for X-shaped radio galaxies compared to existing models as transition objects between cold mode accreting low spinning retrograde black hol…
Catching butterflies in the sky: Extended catalog of winged or X-shaped radio sources from the latest FIRST data release
Xiaolong Yang, Ravi Joshi, Gopal-Krishna +8
We present a catalog of 290 "winged" or X-shaped radio galaxies (XRGs) extracted from the latest (2014 December 17) data release of the "Very Large Array Faint Images of the Radio…
Intranight Optical Variability of Radio-Quiet Weak Emission Line Quasars-IV
Parveen Kumar, Hum Chand, Gopal-Krishna
We report an extension of our program to search for radio-quiet BL Lac candidates using intra-night optical variability (INOV) as a probe. The present INOV observations cover a wel…
Intranight Optical Variability of Radio-Quiet Weak Emission Line Quasars-III
Parveen Kumar, Gopal-Krishna, Hum Chand
This is continuation of our programme to search for the elusive radio-quiet BL Lacs, by carrying out a systematic search for intranight optical variability (INOV) in a subset of `w…
