Intranight optical monitoring of eight quasars with superluminal jets and low optical polarization: Probing the mechanism of rapid flux variability
Krishan Chand, Gopal-Krishna, Ashutosh Tomar +3
Intranight optical variability (INOV) of blazars whose emission arises predominantly from a relativistic jet, has been widely linked to a combination of two key observational diagn…

Probing dust torus radius--luminosity relation: An WISE view
Ashutosh Tomar, Suvendu Rakshit, Amit Kumar Mandal +1
We present measurements of the dusty torus sizes of 51 active galactic nuclei (AGNs) with a redshift of 0.8. Our analysis utilizes about 16 years of optical photometric data o…
