cds-question@unistra.frvisible-astronomyspectroscopyquasarsWe report on the results of a new spectroscopic monitoring campaign of the quasar PG 0026+129 at the Calar Alto Observatory 2.2m telescope from 2017 July to 2020 February. Significant variations in the fluxes of the continuum and broad emission lines, including H{beta} and HeII, were observed in the first and third years, and clear time lags between them are measured. The broad H{beta} line profile consists of two Gaussian components: an intermediate-width H{beta}_IC_ with an FWHM of 1964+/-18km/s and another very broad H{beta}_VBC_ with an FWHM of 7570+/-83km/s. H{beta}_IC_ has long time lags of ~40-60days in the rest frame, while H{beta}_VBC_ shows nearly zero time delay with respect to the optical continuum at 5100{AA}. The velocity-resolved delays show consistent results: lags of ~30-50days at the core of the broad H{beta} line and roughly zero lags at the wings. H{beta}_IC_ has a redshift of ~400km/s, which seems to be stable for nearly 30yr by comparing with archived spectra, and may originate from an infall. The rms spectrum of H{beta}_VBC_ shows a double-peaked profile with brighter blue peak and extended red wing in the first year, which matches the signature of a thin disk. Both the double-peaked profile and the near-zero lag suggest that H{beta}_VBC_ comes from a region associated with the part of the accretion disk that emits the optical continuum. Adopting the FWHM (in the rms spectrum) and the time lag measured for the total H{beta} line, and a virial factor of 1.5, we obtain a virial mass of 2.89_-0.69_^+0.60^x10^7^M_{sun}_ for the central black hole in this quasar.2020ApJ...905...75Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/905/75CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/269/352 : Quasar evolution (Schmidt+, 1983)J/ApJS/140/143 : HST FOS spectral atlas (Bechtold+, 2002)J/AJ/126/1720 : ugriz and H{alpha} of double-peaked AGN (Strateva+, 2003)J/ApJ/613/682 : AGN central masses & broad-line region sizes (Peterson+, 2004)J/AJ/130/381 : Blueshifted [O III] emission (Boroson+, 2005)J/ApJ/683/L115 : Intermediate-line region in quasars (Hu+, 2008)J/ApJ/687/78 : FeII emission in quasars (Hu+, 2008)J/ApJS/189/15 : FeII emission in a sample of AGN spectra (Kovacevic+, 2010)J/ApJS/201/23 : Spectroscopy of 88 z<0.7 SDSS QSOs (Eracleous+, 2012)J/ApJ/782/45 : SEAMBHs.
