  • Changing look AGN Mrk 590: broad-line region and black hole mass from photometric reverberation mapping 
    Amit Kumar Mandal; Schramm, Malte; Rakshit, Suvendu; Stalin, C. S; Vijarnwannaluk, Bovornpratch; Rujopakarn, Wiphu; Poshyachinda, Saran; Kouprianov, Vladimir V; Haislip, Joshua B; Reichar, Daniel E; Sagar, R; Mathew, Blesson (Oxford University Press on behalf of Royal Astronomical Society, 2021-12)
    We present the results of photometric reverberation mapping observations on the changing look active galactic nucleus Mrk 590 at z = 0.026. The observations were carried out from 2018 July to December using broad-band B-, ...
  • An empirical relation to estimate host galaxy stellar light from AGN spectra 
    Jalan, Priyanka; Rakshit, Suvendu; Woo, Jong-Jak; Kotilainen, Jari; Stalin, C. S (Oxford University Press on behalf of Royal Astronomical Society, 2023-05)
    Measurement of black hole mass for low-z (z≤ 0.8) Active Galactic Nuclei (AGNs) is difficult due to the strong contribution from host galaxy stellar light necessitating detailed spectral decomposition to estimate the AGN ...
  • On the origin of core radio emissions from black hole sources in the realm of relativistic shocked accretion flow 
    Das, Santabrata; Nandi, Anuj; Stalin, C. S; Rakshit, Suvendu; Dihingia, Indu Kalpa; Singh, Swapnil; Aktar, Ramiz; Mitra, Samik (Oxford University Press on behalf of Royal Astronomical Society, 2022-08)
    We study the relativistic, inviscid, advective accretion flow around the black holes and investigate a key feature of the accretion flow, namely the shock waves. We observe that the shock-induced accretion solutions are ...
  • Revisiting the Dust Torus Size–Luminosity Relation Based on a Uniform Reverberation-mapping Analysis 
    Mandal, Amit Kumar; Woo, Jong-Hak; Wang, Shu; Rakshit, Suvendu; Cho, Hojin; Son, Donghoon; Stalin, C. S (2024-06-20)
    We investigate the torus size–luminosity relation of Type 1 active galactic nuclei (AGNs) based on the reverberation-mapping analysis using the light curves of the optical continuum and the IR continuum obtained with the ...
  • Spectroscopic reverberation mapping of Quasar PKS 0736 + 017: broad-line region and black-hole mass 
    Pandey, Shivangi; Rakshit, Suvendu; Woo, Jong-Hak; Stalin, C. S (Oxford University Press on behalf of Royal Astronomical Society, 2022-10)
    To understand the mass distribution and co-evolution of supermassive black holes with their host galaxy, it is crucial to measure the black hole mass of AGN. Reverberation mapping is a unique tool to estimate the black ...
