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…
Constraints on axion-like particle properties with very high energy gamma-ray observations of Galactic sources
Yun-Feng Liang, Cun Zhang, Zi-Qing Xia +3
Axion-like particles (ALPs) can oscillate to photons and vice versa in electromagnetic fields. The photon-ALP oscillation provides an attractive solution to the apparent transparen…
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…
Searching for spectral oscillations due to photon-axionlike particle conversion using the Fermi-LAT observations of bright supernova remnants
Zi-Qing Xia, Cun Zhang, Yun-Feng Liang +4
Axionlike-particles (ALPs) are one promising type of dark matter candidate particle that may generate detectable effects on -ray spectra other than the canonical weakly interact…
