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…

Long-term X-ray evolution of SDSS J134244.4+053056.1: A more than 18 year-old, long-lived IMBH-TDE candidate

J. S. He, L. M. Dou, Y. L. Ai +5

SDSS J134244.4+053056 is a tidal disruption event candidate with strong temporal coronal line emitters and a long fading, mid-infrared dust echo. We present detailed analyses of X-…

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…

Infrared Echoes of Optical Tidal Disruption Events: ~1% Dust Covering Factor or Less at sub-parsec Scale

Ning Jiang, Tinggui Wang, Xueyang Hu +3

The past decade has experienced an explosive increase of optically-discovered tidal disruption events (TDEs) with the advent of modern time-domain surveys. However, we still lack a…
