Radio Emission from Fast Blue Optical Transients Powered by Trans-relativistic Shocks in Confined Circumstellar Material
Liang-Duan Liu, Jia-Sen Zhang, Zhao-Sheng Zhang +1
Fast blue optical transients (FBOTs) are luminous, rapidly evolving explosions whose radio emission provides a sensitive probe of shock interaction and the circumstellar material (…
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…
Hard X-ray view of two -ray detected low-luminosity active galactic nuclei: NGC 315 and NGC 4261
Yuwei Yu, Jin Zhang
Aims. The accretion disk of low-luminosity active galactic nuclei (LLAGNs) is a radiatively inefficient accretion flow (RIAF). Our goal is to find evidence of RIAF radiation from L…
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…
X-ray Polarization of the High-Synchrotron-Peaked BL Lac H 1426+428
Xin-Ke Hu, Jia-Xuan Li, Yu-Wei Yu +4
We report the X-ray polarization properties of the high-synchrotron-peaked BL Lac H 1426+428, based on two-epoch observational data from the Imaging X-ray Polarimetry Explorer (IXP…
