High resolution X-ray spectra of the compact binary supersoft X-ray source CAL 87
Songpeng Pei, Xiaowan Zhang, Qiang Li +1
In this study, we present an analysis of the archival X-ray data of the eclipsing supersoft X-ray binary CAL 87 observed with the {\it Chandra} Advanced CCD Imaging Spectrometer (A…
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…
Searching for TeV Candidates in 4LAC High-synchrotron-peaked Frequency BL Lac Objects
K. R. Zhu, S. J. Kang, R. X. Zhou +1
The next generation of TeV detectors is expected to have a significantly enhanced performance. It is therefore constructive to search for new TeV candidates for observation. This p…
The Intrinsic Properties of Multiwavelength Energy Spectra for Fermi Teraelectronvolt Blazars
R. X. Zhou, Y. G. Zheng, K. R. Zhu +1
In this paper, we have selected a sample of 64 teraelectronvolt blazars, with redshift, from those classified in the fourth Fermi Large Area Telescope source catalog\footnote{\url{…
On the origin of GeV spectral break for Fermi blazars: 3C 454.3
Shi-Ju Kang, Yong-Gang Zheng, Qingwen Wu +2
The GeV break in spectra of the blazar 3C 454.3 is a special observation feature that has been discovered by the {\it Fermi}-LAT. The origin of the GeV break in the spectra is stil…
A time-dependent particle acceleration and emission model: Understanding the particle spectral evolution and blazar flares
Y. G. Zheng, S. J. Kang, C. Y. Yang +1
The jets of blazars are renowned for their multi-wavelength flares and rapid extreme variability; however, there are still some important unanswered questions about the physical pr…
