The GeV -ray emission from the composite SNR CTB 87
Yuliang Xin, Jian Tang, Weixiong Ding +3
We report the GeV -ray emission around the composite supernova remnant (SNR) CTB 87 with more than 16 yrs PASS 8 data recorded by the Fermi Large Area Telescope. Two separate po…
Detection of the extended -ray emission from the new supernova remnant G321.3-3.9 with Fermi-LAT
Xiaolei Guo, Xi Liu
With the 15 yrs of Pass 8 data recorded by the {\em Fermi} Large Area Telescope, we report the detection of an extended gigaelectronvolt emission component with a 68\% containment…
Revision of the GeV -ray Emission in the Region of HESS J1813-178 with Fermi-LAT
Xiaolei Guo, Yuliang Xin
HESS J1813-178 is one of the brightest and most compact TeV -ray sources, and whether its -ray emission is associated with supernova remnant (SNR), pulsar wind nebula (PWN) o…
Energy-Dependent Analyses of the Gamma-Ray Emission from HESS J1857+026 with Fermi-LAT
Xiaolei Guo, Xi Liu, Yuliang Xin
We report the discovery of energy-dependent morphology for the GeV gamma-ray emission from HESS J1857+026 with more than 13 years of {\it Fermi} Large Area Telescope (LAT) data. Th…
Detection of the extended -ray emission around supernova remnant DA 530 with Fermi-LAT
Yuliang Xin, Xiaolei Guo
We report the extended GeV -ray emission around the high Galactic latitude supernova remnant (SNR) DA 530 with the PASS 8 data recorded by the Fermi Large Area Telescope (Fermi-…
GeV gamma-ray emission from pulsar wind nebula HESS J1356-645 with Fermi-LAT
Xi Liu, Xiaolei Guo, Yuliang Xin +2
HESS J1356-645 is considered to be a pulsar wind nebula (PWN) associated with the pulsar PSR J1357-6429. We reanalyze the GeV gamma-ray emission in the direction of HESS J1356-645…
Revised the -ray emission from SNR CTB 109 with Fermi-LAT
Yuliang Xin, Qizhen Zhao, Xiaolei Guo
CTB 109 is a middle-aged shell-type SNR with bright thermal X-ray emission. We reanalyze the GeV -ray emission from CTB 109 using thirteen years of Pass 8 data recorded by the F…
Detection of the extended -ray emission from the high Galactic latitude Calvera's SNR candidate
Yuliang Xin, Xiaolei Guo
We report the extended GeV -ray emission that spatially associated with the high Galactic latitude supernova remnant (SNR) candidate - Calvera's SNR with the Pass 8 data recorde…
Flux Variations of Cosmic Ray Air Showers Detected by LHAASO-KM2A During a Thunderstorm on 10 June 2021
LHAASO Collaboration, F. Aharonian, Q. An +268
The Large High Altitude Air Shower Observatory (LHAASO) has three sub-arrays, KM2A, WCDA and WFCTA. The flux variations of cosmic ray air showers were studied by analyzing the KM2A…
Circinus Galaxy Revisted with 10 Years of Fermi-LAT Data
Xiao-Lei Guo, Yu-Liang Xin, Neng-Hui Liao +1
Circinus galaxy is a nearby composite starburst/AGN system. In this work we re-analyze the GeV emission from Circinus with 10 years of {\it Fermi}-LAT Pass 8 data. In the energy ra…
Active galactic nuclei with GeV activities and the PeV neutrino source candidate TXS 0506+056
Neng-Hui Liao, Yu-Liang Xin, Yun-Feng Liang +5
On 2017 September 22 the IceCube neutrino observatory detected a track-like, very-high-energy event (IceCube-170922A) that is spatially associated with TXS 0506+056, a quasar at a…
HESS J1640-465 -- a Gamma-ray emitting pulsar wind nebula ?
Yu-Liang Xin, Neng-Hui Liao, Xiao-Lei Guo +4
HESS J1640-465 is an extended TeV -ray source and its -ray emission whether from the shell of a supernova remnant (SNR) or a pulsar wind nebula (PWN) is still under debate. W…
Detection of GeV -ray emission in the direction of HESS J1731-347 with Fermi-LAT
Xiao-Lei Guo, Yu-Liang Xin, Neng-Hui Liao +3
We report the detection of GeV -ray emission from supernova remnant HESS J1731-347 using 9 years of {\it Fermi} Large Area Telescope data. We find a slightly extended GeV source…
The SNR Puppis A Revisited with Seven Years of Fermi Large Area Telescope Observations
Yu-Liang Xin, Xiao-Lei Guo, Neng-Hui Liao +3
Puppis A is a very famous and extensively studied supernova remnant (SNR) that shows strong evidence of shock-cloud interaction. We re-analyze the GeV -ray emission of it using…
HESS J1427-608: an unusual hard unbroken ray spectrum in a very wide energy range
Xiao-Lei Guo, Yu-Liang Xin, Neng-Hui Liao +5
We report the detection of a GeV -ray source which is spatially overlapping and thus very likely associated with the unidentified very-high-energy (VHE) -ray source HESS J142…
