Shear Particle Acceleration in Structured Gamma-Ray Burst Jets: IV. Thermal {\em vs.} Non-thermal Emission of the Jet Cocoon
Zi-Qi Wang, Xiao-Li Huang, Hai-Ming Zhang +1
A distinct thermal or quasi-thermal spectral component is occasionally observed in gamma-ray burst (GRB) prompt emission spectra. Taking GRB 090902B as a case study, we investigate…
Could the interaction of jet and SN ejecta be the cause of X-ray knots observed in a radio galaxy?
Jia-Chun He, Xiao-Na Sun, Hao-Qiang Zhang +4
We investigate the interaction between relativistic jets and supernova (SN) ejecta as a potential origin of X-ray knots in radio galaxies, employing knot A in M 87 as a test case.…
Ultrahigh-Energy Gamma-ray Emission Associated with Black Hole-Jet Systems
The LHAASO Collaboration, Zhen Cao, Felix Aharonian +315
Black holes (BH), one of the most intriguing objects in the universe, can manifest themselves through electromagnetic radiation initiated by the accretion flow. Some stellar-mass B…
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 Emission Properties of a Compact Symmetric Object Sample
Ying-Ying Gan, Su Yao, Tan-Zheng Wu +2
We present a comprehensive analysis of the X-ray observations obtained from \xmm\, and \chandra\, for a sample of bona-fide Compact Symmetric Objects (CSOs) to investigate their X-…
