Estimating the mass of Narrow Line Seyfert 1 Galaxies using the Damped Random Walk (DRW) Method

Narrow-Line Seyfert 1 galaxies (NLSy1s) are commonly regarded as rapidly accreting, low-mass AGNs, yet uncertainties remain about their true black hole masses, especially for sources with extreme properties. In this study, we analyze ZTF $g$-band light curves for 1,127 NLSy1s and 1,141 BLSy1s, modeling their variability using a Damped Random Walk (DRW) framework. We employ a multivariate calibration incorporating rest-frame wavelength and Eddington ratio to refine black hole mass estimates derived from the charact
