cds-question@unistra.fractive-galactic-nucleivisible-astronomyspectroscopyh-beta-photometryWe report results of the first reverberation mapping campaign of I Zwicky 1 during 2014-2016, which showed unambiguous reverberations of the broad H{beta} line emission in the varying optical continuum. From analysis using several methods, we obtain a reverberation lag of {tau}_H{beta}_=37.2_-4.9_^+4.5^days. Taking a virial factor of f_BLR_=1, we find a black hole mass of M_{bullet}_=9.30_-1.38_^+1.26^x10^6^M_{sun}_ from the mean spectra. The accretion rate is estimated to be 203.9_-65.8_^+61.0^L_Edd_c^-2^, suggesting a super-Eddington accretor, where LEdd is the Eddington luminosity and c is the speed of light. By decomposing Hubble Space Telescope images, we find that the stellar mass of the bulge of its host galaxy is log(M_bulge_/M_{sun}_)=10.92+/-0.07. This leads to a black hole to bulge mass ratio of ~10^-4^, which is significantly smaller than that of classical bulges and elliptical galaxies. After subtracting the host contamination from the observed luminosity, we find that I Zw 1 follows the empirical R_BLR_{propto}L_5100_^1/2^ relation.2019ApJ...876..102Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/876/102CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/269/352 : Quasar evolution (Schmidt+, 1983)J/ApJ/613/682 : AGN central masses & broad-line region sizes (Peterson+, 2004)J/A+A/417/515 : I Zw 1 unusual emission line spectrum (Veron-Cetty+, 2004)J/ApJ/660/1072 : Unified model of active galactic nuclei (Wang+, 2007)J/AJ/136/773 : Structure of classical bulges and pseudobulges (Fisher+, 2008)J/ApJ/687/78 : FeII emission in quasars (Hu+, 2008)J/ApJ/698/895 : Variations in QSOs optical flux (Kelly+, 2009)J/ApJ/782/45 : SEAMBHs.
