Revisiting the constraints on primordial black hole abundance with the isotropic gamma ray background
Siyu Chen, Hong-Hao Zhang, Guangbo Long
We revisit the constraints on primordial black holes (PBHs) in the mass range g by comparing the 100\,keV-5\,GeV gamma-ray background with isotropic flux from PBH…

Searching for an additional high-energy component in Fermi-LAT GRB afterglows
Xin-Bo He, Pak-Hin Thomas Tam, Guang-Bo Long +3
The VHE component from at least two GRBs, i.e., GRB180720B and GRB190114C, has been detected in the afterglow phase. We systematically analyzed 199 GRBs detected by Fermi-LAT durin…

Probing eV ALPs with future LHAASO observation of AGN -ray spectra
Guangbo Long, Siyu Chen, Shuo Xu +1
Axion-like particles (ALPs) are predicted in some well-motivated theories beyond the Standard Model. The TeV gamma-rays from active galactic nuclei (AGN) suffer attenuation by the…
