Modeling the gamma-ray emission in the Galactic Center with a fading cosmic-ray accelerator
Ruo-Yu Liu, Xiang-Yu Wang, Anton Prosekin +1
Recent HESS observations of the ~200 pc scale diffuse gamma-ray emission from the central molecular zone (CMZ) suggest the presence of a PeV cosmic-ray accelerator (PeVatron) locat…
First detection of GeV emission from an ultraluminous infrared galaxy: Arp 220 as seen with the Fermi Large Area Telescope
Fang-Kun Peng, Xiang-Yu Wang, Ruo-Yu Liu +2
Cosmic rays (CRs) in starburst galaxies produce high energy gamma-rays by colliding with the dense interstellar medium (ISM). Arp 220 is the nearest ultra luminous infrared galaxy…
Indication of a Local "Fog" of Sub-Ankle UHECR
Ruo-Yu Liu, Andrew M. Taylor, Xiang-Yu Wang +1
During their propagation through intergalactic space, ultrahigh energy cosmic rays (UHECRs) interact with the background radiation fields. These interactions give rise to energetic…
Testing the equivalence principle and Lorentz invariance with PeV neutrinos from blazar flares
Zi-Yi Wang, Ruo-Yu Liu, Xiang-Yu Wang
It was recently proposed that a giant flare of the blazar PKS B1424-418 at redshift is in association with a PeV-energy neutrino event detected by IceCube. Based on this…
How far are the sources of IceCube neutrinos? Constraints from the diffuse TeV gamma-ray background
Xiao-Chuan Chang, Ruo-Yu Liu, Xiang-Yu Wang
The nearly isotropic distribution of the TeV-PeV neutrinos recently detected by IceCube suggests that they come from sources at distance beyond our Galaxy, but how far they are is…
