Wild behaviour near the finish line: the Type Ibn SN 2020able and its stratified environment
L. Tartaglia, E. Cappellaro, G. Valerin +29
We present spectrophotometric observations of the Type Ibn supernova SN~2020able, along with a comprehensive analysis and modelling of its evolution. The transient occurred in SDSS…
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, a…
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…
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…
Photometric and spectroscopic analysis of the Type II SN 2020jfo with a short plateau
B. Ailawadhi, R. Dastidar, K. Misra +34
We present high-cadence photometric and spectroscopic observations of SN~2020jfo in ultraviolet and optical/near-infrared bands starting from to days after the…
Evidence of jet induced optical microvariability in radio-loud Narrow Line Seyfert 1 Galaxies
Vineet Ojha, Vivek Kumar Jha, Hum Chand +1
To quantify the role of radio jets for Intra-Night Optical Variability (INOV) in Radio-Loud Narrow-Line Seyfert 1 (RLNLSy1) galaxies, we report the first systematic comparative INO…
