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…
Search for line signal candidates in the Fermi-LAT data
Shang Li, Zi-Qing Xia, Yun-Feng Liang +7
In order to search for the line-like signals in the Fermi-LAT data, we have analyzed totally 49152 regions of interest (ROIs) that cover the whole sky. No ROI displays a line signa…
Search for gamma-ray emission from the nearby dwarf spheroidal galaxies with 9 years of Fermi-LAT data
Shang Li, Kai-Kai Duan, Yun-Feng Liang +8
In this work, we search for -ray emission from the directions of some nearby Milky Way dwarf spheroidal galaxies (dSphs) and candidates with the publicly-available Pass 8 data o…
-LAT detection of a transient -ray source in the direction of a distant blazar B3 1428+422 at
Neng-Hui Liao, Shang Li, Yi-Zhong Fan
We report the detection of a transient -ray source in the direction of B3 1428+422 () by analyzing the 110-month {\it Fermi}-LAT Pass 8 data. The new transient ray s…
New Bounds on Axion-Like Particles From the Fermi Large Area Telescope observation of PKS
Cun Zhang, Yun-Feng Liang, Shang Li +5
The axion-like particle (ALP)-photon mixing in the magnetic field around -ray sources or along the line-of-sight could induce oscillation between photons and ALPs, which then ca…
Is the gamma-ray emission around the Coma galaxy cluster a dark matter origin?
Yun-Feng Liang, Zi-Qing Xia, Shao-Qiang Xi +3
Recently, gamma-ray emission in the direction of Coma, with a TS value of , has been reported. In this work we will discuss the possibility of such a residual emission com…
