Image of the Kerr-Newman black hole surrounded by a thin accretion disk
Sen Guo, Yu-Xiang Huang, En-Wei Liang +3
The image of a Kerr-Newman (KN) black hole (BH) surrounded by a thin accretion disk is derived. By employing elliptic integrals and ray-tracing methods, we analyze photon trajector…
Radio Pulsar B095008: Radiation in Magnetosphere and Sparks above Surface
Zhengli Wang, Jiguang Lu, Jinchen Jiang +6
We observed the nearby 100-duty-cycle radio pulsar B0950+08 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We obtained the polarization profile for its…
A Comprehensive Analysis of Insight-HXMT Gamma-Ray Burst Data. I. Power Density Spectrum
Zi-Min Zhou, Xiang-Gao Wang, En-Wei Liang +7
Power Density Spectrum (PDS) is one of the powerful tools to study light curves of gamma-ray bursts (GRBs). We show the average PDS and individual PDS analysis with {\it Hard X-ray…
Polarization degree of magnetic field structure changes caused by random magnetic field in Gamma-ray Burst
Jiang-Chuan Tuo, Hong-Bang Liu, Qian-Nan Mai +4
In a Poynting-flux-dominated (PFD) jet that exhibits an ordered magnetic field, a transition towards turbulence and magnetic disorder follows after magnetic reconnection and energy…
Extended GeV -ray emission around the star forming region of the W3 complex
Qihang Wu, Xiaona Sun, Ruizhi Yang +3
We analyze the GeV -ray emission from the W3 complex using about 14 years of Pass 8 data recorded by the Large Area Telescope (\textit{Fermi}-LAT). We resolve the $…
