Black hole masses of SDSS Seyfert 1 galaxies (Viswanath+, 2019)

Our sources are drawn from the catalog of narrow-line Seyfert 1 galaxies (NLS1s) by Rakshit+ (2017, J/ApJS/229/39). We cross-correlated 11101 NLS1s with the Faint Images of the Radio Sky at Twenty cm (FIRST) survey within a search radius of 2" to find radio-emitting NLS1s. This led us to a sample of 554 NLS1s detected in FIRST, which is around 5% of the total sample of NLS1s. To check for any differences in the derived BH masses of RL-NLS1s, relative to radio-quiet NLS1s (RQ-NLS1s) and BLS1s, we also selected a control sample of RQ-NLS1s and radio-quiet BLS1s (RQ-BLS1). The Shakura-Sunyaev (S&S) accretion disk (AD) model (Shakura & Sunyaev 1973A&A....24..337S) fitting was carried out on RL-NLS1s, RQ-NLS1s, and RQ-BLS1s, each consisting of 554 sources (except for RQ-BLS1s, which contain 471 sources). Of these, our automatic fitting procedure converged for 537 RL and RQ-NLS1s, and 448 RQ-BLS1s.
