Evolution of High-energy Particle Distribution in Supernova Remnants
Houdun Zeng, Yuliang Xin, Qi Fu +1
The spectra fits to a sample of 34 supernova remnants (Zeng et al., 2019) are updated. -ray spectra of 20 supernova remnants (SNRs) with a soft TeV spectrum are further analyzed…
Gamma-ray luminosity function of BL Lac objects and contribution to the extragalactic gamma-ray background
Yankun Qu, Houdun Zeng, Dahai Yan
Using a significantly enlarged \textit{Fermi}-LAT BL Lac objects (BL Lacs) sample, we construct the gamma-ray luminosity function (GLF) of BL Lacs, by the joint use of the space de…
Using the Extragalactic Gamma-Ray Background to Constrain the Hubble Constant and Matter Density of the Universe
Houdun Zeng, Dahai Yan
The attenuation produced by extragalactic background light (EBL) in -ray spectra of blazars has been used to constrain the Hubble constant () and matter density ($Ω_{\rm m}…
The Luminosity Function and Formation Rate of A Complete Sample of Long Gamma-Ray Bursts
Guang-Xuan Lan, Hou-Dun Zeng, Jun-Jie Wei +1
We study the luminosity function and formation rate of long gamma-ray bursts (GRBs) by using a maximum likelihood method. This is the first time this method is applied to a well-de…
VER J2227+608: A Hadronic PeVatron Pulsar Wind Nebula?
Yuliang Xin, Houdun Zeng, Siming Liu +2
We report the detection of GeV -ray emission from the very-high-energy (VHE) -ray source VER J2227+608 associated with the "tail" region of SNR G106.3+2.7. The GeV -ray em…
