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…
Optical monitoring of BL Lac object S5 0716+714 and FSRQ 3C273 from 2000 to 2014
Yu-Hai Yuan, Jun-hui Fan, Jun Tao +5
Using the 1.56m telescope at the Shanghai Observatory (ShAO), China, we monitored two sources, BL Lac object S5 0716+714 and Flat Spectrum Radio Quasar (FSRQ) 3C 273. For S5 0716+7…
The Intrinsic -ray Emissions of Blazars
C. Lin, J. H. Fan, H. B. Xiao
Beaming effect is important for the observational properties of blazars. In this work, we collect 91 blazars with available radio Doppler factors. -ray Doppler factors a…
The Ratio of the Core to the Extended Emissions in the Comoving Frame for Blazars
Yun-Tian Li, Shao-Yu Fu, Huan-Jian Feng +5
In a two-component jet model, the emissions are the sum of the core and extended emissions: , with the core emissions, $S_{\r…
Multi-color optical monitoring of the quasar 3C 273 from 2005 to 2016
Dingrong Xiong, Jinming Bai, Haojing Zhang +4
We have monitored the quasar 3C 273 in optical , and bands from 2005 to 2016. Intraday variability (IDV) is detected on seven nights. The variability amplitudes for most…
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…
Intrinsic Correlations for Flaring Blazars Detected by Fermi
J. H. Fan, J. H. Yang, H. B. Xiao +6
Blazars are an extreme subclass of active galactic nuclei. Their rapid variability, luminous brightness, superluminal motion, and high and variable polarization are probably due to…
The Variability and Period Analysis for the BL Lac AO 0235+164
J. H. Fan, O. Kurtanidze, Y. Liu +12
Variability is one of the extreme observational properties of BL Lacertae objects. AO 0235+164 is a well studied BL Lac through the whole electro-magnetic wavebands. In the present…
