A unified model for orphan and multi-wavelength blazar flares
Ze-Rui Wang, Ruo-Yu Liu, Maria Petropoulou +3
Blazars are a class of active galactic nuclei which host relativistic jets oriented close to the observer's line of sight. Blazars have very complex variability properties. Flares,…
Signatures of linear Breit-Wheeler pair production in polarized collisions
Qian Zhao, Liang Tang, Feng Wan +9
Laser-driven brilliant controllable polarized -photon sources open the way for designing compact collider, which enable the large yield of linear Breit-Wheeler (LBW) pairs…
Fermi-LAT detection of extended gamma-ray emission in the vicinity of SNR G045.700.4: evidence for escaping cosmic rays interacting with the surrounding molecular clouds
Hai-Ming Zhang, Ruo-Yu Liu, Yang Su +3
We present the analysis of Fermi Large Area Telecope (LAT) data of the gamma-ray emission in the vicinity of a radio supernova remnant (SNR), G045.700.4. To study the origin of…
Prospect of Detecting X-Ray Halos Around Middle-Aged Pulsars with eROSITA
Ben Li, Yi Zhang, Ruo-Yu Liu +1
The detection of extended TeV -ray emission (dubbed "TeV halos") from Geminga and Monogem pulsars by HAWC collaboration implies that the halo-like morphologies around middle-age…
Acceleration of ultra-high energy cosmic rays in the early afterglows of gamma-ray bursts: concurrence of jet's dynamics and wave-particle interactions
Ze-Lin Zhang, Ruo-Yu Liu, Xiang-Yu Wang
The origin of ultra-high energy cosmic rays UHECRs remains a mystery. It has been suggested that UHECRs can be produced by the stochastic acceleration in relativistic jets of…
PeV emission of the Crab Nebula: constraints on the proton content in pulsar wind and implications
Ruo-Yu Liu, Xiang-Yu Wang
Recently, two photons with energy of about 1 PeV have been detected by LHAASO from the Crab nebula, opening an ultra-high energy window for studying the pulsar wind nebulae (PWNe).…
