Reverberation Mapping of Two Luminous Quasars: the Broad-line Region Structure and Black Hole Mass

Sha-Sha Li, Sen Yang, Zi-Xu Yang +21

We report the results of a multi-year spectroscopic and photometric monitoring campaign of two luminous quasars, PG~0923+201 and PG~1001+291, both located at the high-luminosity en…

Standardizing reverberation-measured Mg II time-lag quasars, by using the radius-luminosity relation, and constraining cosmological model parameters

Narayan Khadka, Zhefu Yu, Michal Zajaček +3

We use 78 reverberation-measured Mg II time-lag quasars (QSOs) in the redshift range to constrain cosmological parameters in six different cosmological mo…

Faint AGNs Favor Unexpectedly Long Inter-band Time Lags

Ting Li, Mouyuan Sun, Xiaoyu Xu +12

Inconsistent conclusions are obtained from recent active galactic nuclei (AGNs) accretion disk inter-band time-lag measurements. While some works show that the measured time lags a…

OzDES Reverberation Mapping Program: The first Mg II lags from five years of monitoring

Zhefu Yu, Paul Martini, A. Penton +63

Reverberation mapping is a robust method to measure the masses of supermassive black holes (SMBHs) outside of the local Universe. Measurements of the radius -- luminosity () r…

OzDES Reverberation Mapping Program: Lag recovery reliability for 6-year CIV analysis

Andrew Penton, Umang Malik, Tamara Davis +66

We present the statistical methods that have been developed to analyse the OzDES reverberation mapping sample. To perform this statistical analysis we have created a suite of custo…

Evidence for Two Distinct Broad-Line Regions from Reverberation Mapping of PG 0026+129

Chen Hu, Sha-Sha Li, Wei-Jian Guo +17

We 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 July 2017 to February 2020. Signific…
