Mid-InfraRed Outbursts in Nearby Galaxies (MIRONG). II. Optical Spectroscopic Follow-up
Yibo Wang, Ning Jiang, Tinggui Wang +8
Infrared echo has proven to be an effective means to discover transient accretion events of supermassive black holes (SMBHs), such as tidal disruption events (TDEs) and changing-lo…
Evidence of a tidal disruption event in GSN 069 from the abnormal carbon and nitrogen abundance ratio
Zhenfeng Sheng, Tinggui Wang, Gary Ferland +4
GSN 069 is an ultra-soft X-ray active galactic nucleus that previously exhibited a huge X-ray outburst and a subsequent long-term decay. It has recently presented X-ray quasi-perio…
Mrk 1239: a Type-2 Counterpart of Narrow-line Seyfert-1?
Xiang Pan, Hongyan Zhou, Chenwei Yang +10
We present new spectrophotometric and spectropolarimetric observations of Mrk 1239, one of the 8 prototypes that defines type-1 narrow-line Seyfert galaxies (NLS1s). Unlike the oth…
