Probing the -ray Emission Origin of Two Star-forming Galaxies NGC 2403 and NGC 3424 with the Fermi-LAT
Linjie Liu, Wei Zhang, Xian Hou +1
Star-forming galaxies (SFGs) are a subclass of -ray emitters and a correlation between their -ray luminosity () and the total infrared (IR) luminosity ($L_{\rm…
The -ray-emitting blazar B3 1239+376 at = 3.82 identified in a multi-wavelength context
Wei Zhang, Neng-Hui Liao, Hao-Yi Huang +6
Among thousands of extragalactic -ray emitters, only a handful of distant ( 3) sources are detected. Yet, they are crucial probes shedding light on the cosmic evolution of…
The First GeV Gamma-Ray Flares from the CSO-like Source 4C 76.03
Xiong Jiang, Hai Lei, Hao-Yi Huang +3
We report the first detection of GeV gamma-ray flaring activity from the compact symmetric object (CSO)-like source 4C 76.03, based on 17 years of Fermi-LAT observations. Its long-…
Gamma-ray Analysis of Pulsar Environments and Their Theoretical Explanation
Wei Zhang
Pulsars and their pulsar wind nebulae (PWNe) are unique laboratories for extreme astrophysical processes. This dissertation combines Fermi-LAT observations with a time-dependent le…
