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.…

On the origin of a possible hard VHE spectrum from M87 discovered by LHAASO
Rui Xue, Jia-Chun He, Dingrong Xiong +1
Recent LHAASO observations hint at potential spectral hardening around 20 TeV in M87's very high energy (VHE) emission, suggesting a possible new radiation component. In this work,…

Studying X-ray spectra from large-scale jets of FR II radio galaxies: application of shear particle acceleration
Jia-Chun He, Xiao-Na Sun, Jie-Shuang Wang +3
Shear particle acceleration is a promising candidate for the origin of extended high-energy emission in extra-galactic jets. In this paper, we explore the applicability of a shear…
