Searching for -ray emission from a bona fide Compact Symmetric Object sample: a -ray signal near GB6 J0906+4124
Ying-Ying Gan, Kai Wang, Ji-Shun Lian +1
As a particular subclass of active galactic nuclei (AGNs), compact symmetric objects (CSOs) have attracted significant attention due to potential role as young AGNs. Several -r…
Fast Optical Variability of the TeV Blazar PKS 1725+123 Observed by SVOM-VT and Insights from Multi-wavelength Follow-up Observations
Shuo-Yu Liu, Yu-Wei Yu, Ji-Shun Lian +29
PKS 1725+123 is a flat-spectrum radio quasar (FSRQ) with a redshift of . The detection of this object in the TeV band was reported by the MAGIC telescopes and H.E.S.S. in…
Spectral Variations of -rays in Mrk 421
Rui-Qi Huang, Xin-Ke Hu, Yu-Wei Yu +2
We present a comprehensive analysis of the 17-year Fermi-LAT observational data of Mrk 421 to investigate the spectral variations in the -ray bands. The light curve of the sour…
Properties and Possible Physical Origins of -ray Emission in Extreme Synchrotron Blazars
Ji-Shun Lian, Jia-Xuan Li, Ze-Rui Wang +3
Extreme synchrotron blazars, characterized by a first peak in their broadband spectral energy distributions (SEDs) at frequencies exceeding Hz, often exhibit a second pea…
Hadronic Processes in Advection-Dominated Accretion Flow as the Origin of TeV Excesses in BL Lac Objects
Ji-Shun Lian, Ze-Rui Wang, Jin Zhang
The spectral energy distributions (SEDs) of certain BL Lac objects (BL Lacs) exhibit an additional hard -ray component in the TeV energy range that surpasses the predictions of…
Two-Component gamma-ray Emission Spectrum and X-Ray Polarization of the Radio Galaxy Pictor A
Jia-Xuan Li, Xin-Ke Hu, Ji-Shun Lian +6
Pictor A is a -ray emitting radio galaxy and has a bright hotspot called WHS, located 4 arcmin away from the nucleus. In this work, we present an analysis of its 16-year…
