Anisotropic Diffusion in Pulsar Halos: Interpreting the asymmetric morphology of Geminga and Monogem halos measured by HAWC
Si-Zhe Wu, Chao-Ming Li, Ruo-Yu Liu
Pulsar halos are produced by electrons and positrons diffusing in the interstellar medium around their parent pulsar wind nebulae. Recent observations by HAWC and LHAASO have revea…
TeV Gamma-Rays from the Low-Luminosity Active Galactic Nucleus NGC 4278: Implications for the Diffuse Neutrino Background
Chengchao Yuan, Ruo-Yu Liu
This work investigates the origin of the TeV emission detected by the Large High Altitude Air Shower Observatory (LHAASO) from NGC~4278, a galaxy hosting a low-luminosity active ga…
Diagnosing Interstellar Magnetic Turbulence with TeV Pulsar Halos
Chao-Ming Li, Ruo-Yu Liu, Huirong Yan
Interstellar magnetic field is essential in various astrophysical phenomena and processes. Pulsar halos are a recently discovered class of TeV gamma-ray sources formed by escaping…
A Leptonic Interpretation of the UHE Gamma-ray Emission from V4641 Sgr
Su-Yu Wan, Jie-shuang Wang, Ruo-Yu Liu
Recently, the microquasar V4641 Sgr and its surrounding is detected at TeV-PeV gamma-ray band. Interestingly, the spectrum follows a power-law function continuing up to 0.8 PeV as…
Pulsar+escape: the recipe for LHAASO sources ?
Pierrick Martin, Inès Mertz, Jean Kempf +3
Observations of our Galaxy at very-high and ultra-high photon energies have revealed a rich population of sources, many of which have significant angular extension and/or are posit…
Interpreting the multi-TeV emission from GRB 221009A with a second electron component accelerated by turbulence in the jet
Xing-Wei Gong, Ruo-Yu Liu, Ze-Lin Zhang +2
The detection of very high-energy (VHE) afterglow emission of the gamma-ray burst (GRB) 221009A by the Large High Altitude Air Shower Observatory (LHAASO) provides a unique opportu…
