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…
Optimization of performance of the KM2A full array using the Crab Nebula
LHAASO collaboration
The full array of the Large High Altitude Air Shower Observatory (LHAASO) has been in operation since July 2021. For its kilometer-square array (KM2A), we have optimized the select…
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…
