Constraints on the Model of Gamma-ray Bursts and Implications from GRB 221009A: GeV gamma rays v.s. High-energy Neutrinos
Ruo-Yu Liu, Hai-Ming Zhang, Xiang-Yu Wang
Gamma-ray bursts (GRB) are generally believed to be efficient particle accelerators. In the presence of energetic protons in a GRB jet, interactions between these protons and inten…
On the Hadronic Origin of High Energy Emission of -ray Loud Narrow-Line Seyfert 1 PKS 1502+036
Zhen-Jie Wang, Ze-Rui Wang, Ruo-Yu Liu +1
The radiation mechanism of Radio-Loud Narrow-Line Seyfert 1 (RL-NLS1) from X-ray to -ray bands remains an open question. While the leptonic model has been employed to explain th…
A PeVatron Candidate: Modelling the Boomerang Nebula in X-ray Band
Xuan-Han Liang, Chao-Ming Li, Qi-Zuo Wu +2
Pulsar wind nebula (PWN) Boomerang and the associated supernova remnant (SNR) G106.3+2.7 are among candidates for the ultra-high-energy (UHE) gamma-ray counterparts published by LH…
Choked jets in expanding envelope as the origin of the neutrino emission associated with Tidal Disruption Events
Jian-He Zheng, Ruo-Yu Liu, Xiang-Yu Wang
Three tidal disruption event (TDE) candidates (AT2019dsg, AT2019fdr, AT2019aalc) have been found to be coincident with high-energy astrophysical neutrinos in multi-messenger follow…
Detection of GeV emission from an ultra-long gamma-ray burst with the Fermi Large Area Telescope
Yi-Yun Huang, Hai-Ming Zhang, Kai Yan +2
GRB 220627A, detected by Fermi Gamma-ray Burst Monitor (GBM), shows two episodes of gamma-ray emission, which are separated by a {700} s long quiescent phase. Due to similar…
Detection of diffuse gamma-ray emission towards a massive star forming region hosting Wolf-Rayet stars
Kai Wang, Hai-Ming Zhang, Ruo-Yu Liu +1
Isotopic and elemental abundances seen in Galactic cosmic rays imply that of the cosmic-ray (CR) nuclei are probably synthesized by massive Wolf-Rayet (WR) stars. Massiv…
The Physics of Pulsar Halos: Research Progress and Prospect
Ruo-Yu Liu
Diffusive TeV gamma-ray emissions have been recently discovered extending beyond the pulsar wind nebulae of a few middle-aged pulsars, implying that energetic electron/positron pai…
High-energy neutrinos and gamma rays from winds and tori in active galactic nuclei
Susumu Inoue, Matteo Cerruti, Kohta Murase +1
Powerful winds with wide opening angles, likely driven by accretion disks around black holes (BHs), are observed in the majority of active galactic nuclei (AGN) and can play a cruc…
Prospect of detecting TeV halos with LHAASO: in the framework of the anisotropic diffusion model
Kai Yan, Ruo-Yu Liu, S. Z. Chen +1
The particle diffusion coefficients of three TeV pulsar halos observed so far are inferred to be significantly smaller than the typical value of the interstellar medium (ISM). The…
Fermi-LAT Detection of a GeV Afterglow from a Compact Stellar Merger
Hai-Ming Zhang, Yi-Yun Huang, Jian-He Zheng +2
It is usually thought that long-duration gamma-ray bursts (GRBs) are associated with massive star core collapse, whereas short-duration GRBs are associated with mergers of compact…
A semi-analytical solution to the forward-reverse shock hydrodynamics of the gamma-ray burst afterglow
Ze-Lin Zhang, Ruo-Yu Liu, Jin-Jun Geng +2
We extend the standard model of forward-reverse shock (FS-RS) for gamma-ray burst (GRB) afterglow to more general cases. On one hand, we derive the analytical solution to the hydro…
Interpretation of the light curve of GeV-TeV emission from the 2021 outburst of the recurrent nova RS Ophiuchi
Jian-He Zheng, Yi-Yun Huang, Ze-Lin Zhang +3
Nova outbursts take place in binary star systems comprising a white dwarf (WD) and either a low-mass Sun-like star (classical novae) or, a red giant. GeV gamma-ray emission has bee…
Constraining the baryon loading factor of AGN jets: implication from the gamma-ray emission of the Coma cluster
Xin-Yue Shi, Yi Zhang, Ruo-Yu Liu +1
High-energy cosmic rays (CRs) can be accelerated in the relativistic jets of Active Galactic Nuclei (AGNs) powered by supermassive black holes. The baryon loading efficiency onto r…
