X-ray spectral shape variations in changing-look Seyfert galaxy SDSSJ155258+273728
Yanli Ai, Liming Dou, Chenwei Yang +7
We analyze the X-ray, optical, and mid-infrared data of a "changing-look" Seyfert galaxy \sdssj15 at . Over a period of one decade (2009 - 2018), its broad H line…
Initial results from a systematic search for changing-look active galactic nuclei selected via mid-infrared variability
Zhenfeng Sheng, Tinggui Wang, Ning Jiang +6
Changing look active-galatic-nuclei (CL AGNs) can yield considerable insight into accretion physics as well as the co-evolution of black holes and their host galaxies. A large samp…
Rapid "Turn-on" of type 1 AGN in a quiescent early type galaxy SDSS1115+0544
Lin Yan, Tinggui Wang, Jiang Ning +8
We present a detailed study of a transient in the center of SDSS1115+0544 based on the extensive UV, optical, mid-IR light curves (LC) and spectra over 1200 days. The host galaxy i…
Multi-wavelength variability of CGRaBS J0733+0456: identifying a distant -ray blazar at z = 3.01
Neng-Hui Liao, Li-Ming Dou, Ning Jiang +3
We report on OVRO, WISE, Swift and Fermi-LAT observations of the high redshift blazar CGRaBS J0733+0456, from which significant flux variations in radio, infrared (IR) as well as $…
