Gamma-ray Emission from the S147 Region: Indication of Escaping Cosmic Rays Interacting with Molecular Clouds
Huan Yang, Bing Liu, Houdun Zeng +1
We present a detailed analysis of -ray emission from the middle-aged supernova remnant (SNR) S147 (G180.01.7) using approximately 16.5 years of Fermi-LAT data. Spatially, a…
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…
Constraining the Luminosity Function and Delay-Time Distribution of Short Gamma-Ray Bursts for Multimessenger Gravitational-Wave Detection Rate Estimation
Chong-Yu Gao, Jun-Jie Wei, Hou-Dun Zeng
In this work, we analyze the most recent short gamma-ray burst (sGRB) sample detected by the \emph{Fermi} satellite to reassess the sGRB luminosity function and formation rate. Usi…
Broadband -ray spectrum of supernova remnant Cassiopeia A
Zhen Cao, F. Aharonian, Y. X. Bai +311
The core-collapse supernova remnant (SNR) Cassiopeia A (Cas A) is one of the brightest galactic radio sources with an angular radius of 2.5 $\arcmin$. Although no extension…
