Mid-infrared variability of changing-look AGN

Zhenfeng Sheng, Tinggui Wang, Ning Jiang +4

It is known that some active galactic nuclei (AGNs) transited from type 1 to type 2 or vice versa. There are two explanations for the so-called changing look AGNs: one is the drama…

Carbon and Nitrogen Abundance Ratio In the Broad Line Region of Tidal Disruption Events

Chenwei Yang, Tinggui Wang, Gary J. Ferland +4

The rest-frame UV spectra of three recent tidal disruption events (TDEs), ASASSN-14li, PTF15af and iPTF16fnl display strong nitrogen emission lines but weak or undetectable carbon…

Discovery of a Mid-infrared Echo from the TDE candidate in the nucleus of ULIRG F01004-2237

Liming Dou, Tinggui Wang, Lin Yan +5

We present the mid-infrared (MIR) light curves (LCs) of a tidal disruption event (TDE) candidate in the center of a nearby ultraluminous infrared galaxy (ULIRG) F01004-2237 using a…
