The Third Data Release of the Beijing-Arizona Sky Survey
Hu Zou, Xu Zhou, Xiaohui Fan +45
The Beijing-Arizona Sky Survey (BASS) is a wide and deep imaging survey to cover a 5400 deg area in the Northern Galactic Cap with the 2.3m Bok telescope using two filters (…
An Unusual Mid-Infrared Flare in a Type 2 AGN: An Obscured Turning-on AGN or Tidal Disruption Event?
Qian Yang, Yue Shen, Xin Liu +5
We report the discovery of an exceptional MIR flare in a Type 2 AGN, SDSS J165726.81+234528.1, at . This object brightened by 3 mag in the Wide-field Infrared Survey Explo…
Understanding Broad Mg II Variability in Quasars with Photoionization: Implications for Reverberation Mapping and Changing-Look Quasars
Hengxiao Guo, Yue Shen, Zhicheng He +7
The broad Mg II line in quasars has distinct variability properties compared with broad Balmer lines: it is less variable, and usually does not display a "breathing" mode, the incr…
Spectral Variability of a Sample of Extreme Variability Quasars and Implications for the MgII Broad-line Region
Qian Yang, Yue Shen, Yu-Ching Chen +49
We present new Gemini/GMOS optical spectroscopy of 16 extreme variability quasars (EVQs) that dimmed by more than 1.5 mag in the band between the Sloan Digital Sky Survey (SDSS…
Mapping the Inner Structure of Quasars with Time-Domain Spectroscopy
Yue Shen, Scott Anderson, Edo Berger +40
The ubiquitous variability of quasars across a wide range of wavelengths and timescales encodes critical information about the structure and dynamics of the circumnuclear emitting…
