On the minimum jet power of TEV BL Lac objects in the p- model
Rui Xue, Ruo-Yu Liu, Xiang-Yu Wang +2
We study the requirement on the jet power in the conventional p- models (photopion production and Bethe-Heitler pair production) for TeV BL Lac objects. We select a sample of Te…
GeV observations of the extended pulsar wind nebulae constrain the pulsar interpretations of the cosmic-ray positron excess
Shao-Qiang Xi, Ruo-Yu Liu, Zhi-Qiu Huang +2
It has long been suggested that nearby pulsars within are the leading candidate of the 10-500 GeV cosmic-ray positron excess measured by PAMELA and other exper…
Jet-cloud/star interaction as an interpretation of neutrino outburst from the blazar TXS 0506+056
Kai Wang, Ruo-Yu Liu, Zhuo Li +2
A neutrino outburst between September 2014 and March 2015 was discovered from the blazar TXS 0506+056 by an investigation of years of IceCube data, while the blazar was in a…
A hadronuclear interpretation of a high-energy neutrino event coincident with a blazar flare
Ruo-Yu Liu, Kai Wang, Rui Xue +4
Although many high-energy neutrinos detected by the IceCube telescope are believed to have anextraterrestrial origin, their astrophysical sources remain a mystery. Recently, an unp…
Inefficient cosmic ray diffusion around Vela X : constraints from H.E.S.S. observations of very high-energy electrons
Zhi-Qiu Huang, Kun Fang, Ruo-Yu Liu +1
Vela X is a nearby pulsar wind nebula (PWN) powered by a year old pulsar. Modeling of the spectral energy distribution of the Vela X PWN has shown that accelerated elec…
Analytical treatment for the development of electromagnetic cascades in intense magnetic fields
Jie-Shuang Wang, Ruo-Yu Liu, Felix Aharonian +1
In a strong magnetic field, a high-energy photon can be absorbed and then produce an electron-positron pair. The produced electron/positron will in turn radiate a high-energy photo…
Gamma-ray Production in the Extended Halo of the Galaxy and Possible Implications for the Origin of Galactic Cosmic Rays
Ruo-Yu Liu, Huirong Yan, Xiang-Yu Wang +2
Various studies have implied the existence of a gaseous halo around the Galaxy extending out to 100 kpc. Galactic cosmic rays (CRs) that propagate to the halo, either by diffusion…
Hadronic origin of prompt high-energy emission of gamma-ray bursts revisited: in the case of a limited maximum proton energy
Kai Wang, Ruo-Yu Liu, Zi-Gao Dai +1
The high-energy (> 100MeV) emission observed by Fermi-LAT during the prompt phase of some luminous gamma-ray bursts (GRBs) could arise from the cascade induced by interactions betw…
