Probing jet-induced optical variability across timescales in radio-loud NLSy1 galaxies
Vivek Kumar Jha, Anshul Kumar Sharma, Madhu Sudan +1
We investigate optical variability across multiple timescales in a sample of radio-loud narrow-line Seyfert~1 (RL-NLSy1) galaxies, including -ray detected, -ray undetected,…

Do Low-Mass, Low-Luminosity AGNs Deviate from the Quasar Main Sequence?
Himanshu Sharma, Vivek Kumar Jha, Hum Chand +1
We present a comprehensive spectroscopic and variability-based characterisation of a sample of low-luminosity active galactic nuclei (AGNs) hosting low mass black holes, identified…

Exploring the Origins of Optical Variability in AGNs: Correlations with Black Hole Properties, X-ray, and Radio Emission
Vivek Kumar Jha, Debbijoy Bhattacharya, Hum Chand
We study the optical variability characteristics of Active Galactic Nuclei (AGN) from the Swift Burst Alert Telescope (BAT) AGN catalogue by utilising approximately five years of o…
