Very High Energy Emission and Cascade Radiation of Gamma-Ray Burst Afterglows: Homogeneous Versus Wind External Media
Xiao-Li Huang, Ze-Rui Wang, Ruo-Yu Liu +2
Recent detection of sub-TeV emission from gamma-ray bursts (GRBs) represents a breakthrough in the GRB study. The multi-wavelength data of the afterglows of GRB 190114C support the…
Revealing a peculiar supernova remnant G106.3+2.7 as a petaelectronvolt proton accelerator with X-ray observations
Chong Ge, Ruo-Yu Liu, Shu Niu +2
Supernova remnants (SNRs) have long been considered as one of the most promising sources of Galactic cosmic rays. In the SNR paradigm, petaelectronvolt (PeV) proton acceleration ma…
Neutrino Emission from an Off-Axis Jet Driven by the Tidal Disruption Event AT2019dsg
Ruo-Yu Liu, Shao-Qiang Xi, Xiang-Yu Wang
Recently, a high-energy muon neutrino event was detected in association with a tidal disruption event (TDE) AT2019dsg at the time about 150 days after the peak of the optical/UV lu…
A two-zone blazar radiation model for "orphan" neutrino flares
Rui Xue, Ruo-Yu Liu, Ze-Rui Wang +2
In this work, we investigate the 2014-2015 neutrino flare associated with the blazar TXS 0506+056 and a recently discovered muon neutrino event IceCube-200107A in spatial coinciden…
Afterglow Synchrotron Radiations follow the relation of Gamma-Ray Bursts? Cases of GRBs 190114C, 130427A, and 180720B
Xiao-Li Huang, En-Wei Liang, Ruo-Yu Liu +2
Bimodal spectral energy distributions (SEDs) of gamma-ray burst (GRB) afterglow of GRBs 190114C, 130427A and 180720B confirm that they are originated from the synchrotron emission…
Morphology of Gamma-Ray Halos around Middle-Aged Pulsars: Influence of the Pulsar Proper Motion
Yi Zhang, Ruo-Yu Liu, S. Z. Chen +1
Recently, gamma-ray halos of a few degree extension have been detected around two middle-aged pulsars, namely, Geminga and PSR B0656+14, by the High Altitude Water Cherenkov observ…
Measuring the Mass of Missing Baryons in the Halo of Andromeda Galaxy with Gamma-Ray Observations
Yi Zhang, Ruo-Yu Liu, Hui Li +4
One of the biggest mysteries in the modern cosmology and galaxy formation is the hideout of the "missing baryons". The leading theory of galaxy formation predicts that a huge amoun…
Limiting Superluminal Neutrino Velocity and Lorentz Invariance Violation by Neutrino Emission from the Blazar TXS 0506+056
Kai Wang, Shao-Qiang Xi, Lijing Shao +3
The detection of high-energy neutrino coincident with the blazar TXS 0506+056 provides a unique opportunity to test Lorentz invariance violation (LIV) in the neutrino sector. Thank…
Gamma-ray heartbeat powered by the microquasar SS 433
Jian Li, Diego F. Torres, Ruo-Yu Liu +3
Microquasars, the local siblings of extragalactic quasars, are binary systems comprising a compact object and a companion star. By accreting matter from their companions, microquas…
Magnetar giant flare origin for GRB 200415A inferred from a new scaling relation and its implications
Hai-Ming Zhang, Ruo-Yu Liu, Shu-Qing Zhong +1
Soft gamma-ray repeaters (SGRs) are mainly a Galactic population and originate from neutron stars with intense () magnetic fields ('magnetars'). Occasiona…
Chandra and XMM-Newton observations of A2256: cold fronts, merger shocks, and constraint on the IC emission
Chong Ge, Ruo-Yu Liu, Ming Sun +13
We present the results of deep Chandra and XMM-Newton observations of a complex merging galaxy cluster Abell 2256 (A2256) that hosts a spectacular radio relic (RR). The temperature…
A serendipitous discovery of GeV gamma-ray emission from supernova 2004dj in a survey of nearby star-forming galaxies with Fermi-LAT
Shao-Qiang Xi, Ruo-Yu Liu, Xiang-Yu Wang +3
The interaction between a supernova ejecta and the circum-stellar medium drives a strong shock wave which accelerates particles (i.e., electrons and protons). The radio and X-ray e…
GeV -ray emission from M33 and Arp~299
Shao-Qiang Xi, Hai-Ming Zhang, Ruo-Yu Liu +1
Star-forming galaxies are huge reservoirs of cosmic rays (CRs) and these CRs convert a significant fraction of their energy into -rays by colliding with the interstellar medium…

Zhi-Qiu Huang, Ruo-Yu Liu, Jagdish C. Joshi +1
Measurements of cosmic-ray (CR) positron fraction by PAMELA and other experiments have found an excess above 10 GeV relative to the standard predictions for secondary production in…
Constraints on the intergalactic magnetic field from -ray observations of GRB 190114C
Ze-Rui Wang, Shao-Qiang Xi, Ruo-Yu Liu +2
Very high energy photons from cosmological gamma-ray bursts (GRBs) are expected to interact with extragalactic background light (EBL) and produce electron-positron pairs when they…
