A Radio Changing-state Jet in the Narrow-line Seyfert 1 Galaxy J1105+1452
Liming Dou, Zhining Chen, Jiahua Wu +9
We report the discovery of a radio-quiet to radio-loud transition in the narrow-line Seyfert 1 galaxy J1105+1452. The source has undergone a long-term evolution from a radio-quiet…
Introduction to the Chinese Space Station Survey Telescope (CSST)
CSST Collaboration, Yan Gong, Haitao Miao +119
The Chinese Space Station Survey Telescope (CSST) is an upcoming Stage-IV sky survey telescope, distinguished by its large field of view (FoV), high image quality, and multi-band o…
The Physical Properties of Changing-look Blazars
Shi-Ju Kang, Bing Lyu, Qingwen Wu +2
Changing-look active galactic nuclei (AGNs) are a special class of AGNs that change their spectral type from type 1 to type 2 or vice versa. In recent years, a number of changing-l…
Optical flux and spectral variability of BL Lacertae during its historical high outburst in 2020
Nibedita Kalita, Yuhai Yuan, Minfeng Gu +9
BL Lacertae had undergone a series of historical high flux activity over a year, from August 2020 in the optical to VHE -rays. In this paper, we report on optical flux and spec…
Systematic Search and Study of Short-Timescale Flare Structures in BL Lac object Gamma-ray Emission
Jinjie Yu, Nan Ding, Junhui Fan +2
We present here the first systematic search of short timescale -ray flares from 29 high Galactic latitude BL Lac objects over 14 years of Fermi Large Area Telescope data. Using…
Constraining the -ray Emission Region for Fermi-Detected FSRQs by the Seed Photon Approach
Danyi Huang, Ziyan Li, Jiru Liao +5
The location of -ray emitting region in blazars has been an open issue for several decades and is still being debated. We use the Paliya et al. sample of 619 -ray-loud flat…
