Awakening of two -ray high redshift flat-spectrum radio quasars in the southern hemisphere
Shang Li, Lu-Ming Sun, Neng-Hui Liao +1
High-redshift blazars are valuable tools to study the early Universe. So far only a handful of -ray blazars have been found at redshifts above 3. -ray signals are detected in…
A Mid-infrared Flare in the Active Galaxy MCG-02-04-026: Dust Echo of a Nuclear Transient Event
Luming Sun, Ning Jiang, Tinggui Wang +8
We report the discovery of a mid-infrared (MIR) flare using WISE data in the center of the nearby Seyfert 1.9 galaxy MCG-02-04-026. The MIR flare began in the first half of 2014, p…
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…
Timing analysis of 2S 1417-624 observed with NICER and Insight-HXMT
L. Ji, V. Doroshenko, A. Santangelo +112
We present a study of timing properties of the accreting pulsar 2S 1417-624 observed during its 2018 outburst, based on Swift/BAT, Fermi/GBM, Insight-HXMT and NICER observations. W…
Hot disk of the Swift J0243.6+6124 revealed by Insight-HXMT
V. Doroshenko, S. N. Zhang, A. Santangelo +113
We report on analysis of observations of the bright transient X-ray pulsar \src obtained during its 2017-2018 giant outburst with Insight-HXMT, \emph{NuSTAR}, and \textit{Swift} ob…
Massive Neutral Gas Outflow in Reddened Quasar SDSS J072910.34+333634.3
Tong Liu, Luming Sun, Xiang Pan +1
SDSS J072910.34+333634.3 is a reddened quasar at z=0.96. The archivel Keck/ESI spectrum and our new P200/TripleSpec spectrum reveal an absorption line system in He I*, Ca II H\&K a…
