Detection of time delay between UV and X-ray variability in Mrk 1044 using AstroSat observations
M. Reshma, C. S. Stalin, Amit Kumar Mandal +3
Active galactic nuclei are known to exhibit flux variations across the entire electromagnetic spectrum. Among these, correlations between UV/optical and X-ray flux variations serve…
Spectrophotometric reverberation mapping of Intermediate-mass black hole NGC 4395
Shivangi Pandey, Suvendu Rakshit, Krishan Chand +8
Understanding the origins of massive black hole seeds and their co-evolution with their host galaxy requires studying intermediate-mass black holes (IMBHs) and estimating their mas…
Revisiting the dust torus size-luminosity relation based on a uniform reverberation mapping analysis
Amit Kumar Mandal, Jong-Hak Woo, Shu Wang +4
We investigate the torus size -- luminosity relation of Type 1 AGNs based on the reverberation-mapping analysis using the light curves of the optical continuum and the IR continuum…
Identifying changing-look AGNs using variability characteristics
Shu Wang, Jong-Hak Woo, Elena Gallo +7
Changing-look (CL) Active Galactic Nuclei (AGNs), characterized by appearance/disappearance of broad emission lines in the span of a few years, present a challenge for the AGN unif…
The Seoul National University AGN Monitoring Project III: H lag measurements of 32 luminous AGNs and the high-luminosity end of the size--luminosity relation
Jong-Hak Woo, Shu Wang, Suvendu Rakshit +28
We present the main results from a long-term reverberation mapping campaign carried out for the Seoul National University Active Galactic Nuclei (AGN) Monitoring Project. High-qual…
The Seoul National University AGN Monitoring Project IV: H reverberation mapping of 6 AGNs and the H Size-Luminosity Relation
Hojin Cho, Jong-Hak Woo, Shu Wang +29
The broad line region (BLR) size-luminosity relation has paramount importance for estimating the mass of black holes in active galactic nuclei (AGNs). Traditionally, the size of th…
