The Apparent Asymmetric Outflows of TeV Particles from Pulsar Winds
HongYu Pu, Siming Liu
Observations of X-ray filaments attached to a couple of powerful pulsars suggest escape of TeV electrons and/or positrons (e) from pulsar bow shocks into surrounding large…
Discovery of diffuse gamma-ray emission in the vicinity of G172.8+1.5: An old supernova remnant with different turbulence properties
Yuan Li, Gwenael Giacinti, Siming Liu
We report the detection of high-energy -ray emission in the vicinity of G172.8+1.5, which is debated as a Supernova remnant (SNR) or an ionized hydrogen (H) region.…
Discovery of diffuse -ray emission in the vicinity of G213.0-0.6: Supernova remnant versus massive star-forming region
Yuan Li, Gwenael Giacinti, Siming Liu
We report the discovery of high-energy -ray emission in the vicinity of G213.0-0.6, which is debated as a supernova remnant (SNR) or an ionized hydrogen (H) region.…
Influence of interstellar environment near the solar system on cosmic-ray spectra and dipole anisotropy
Zhangxi Xue, Siming Liu
Properties of interstellar environment near the solar system have been probed by missions like IBEX, Voyager over the last two decades. Although it has been well recognized that pr…
-Cygni supernova remnant in -rays: signatures of trapped and escaped Cosmic Rays
Yuan Li, Gwenael Giacinti, Siming Liu +1
We reanalyze 15 years of data recorded by the Fermi Large Area Telescope in a region around supernova remnant (SNR) -Cygni from 100 MeV to 1 TeV, and find that the spectra of t…
