Evidence for GeV emission of the superluminous supernova SN 2017egm
Shang Li, Yun-Feng Liang, Neng-Hui Liao +2
Superluminous supernovae (SLSNe) are a new class of transients with luminosities times larger than the usual core-collapse supernovae (SNe). Their origin is still unc…
Search for gamma-ray emission from the 12 nearby dwarf spheroidal galaxies with 12 years of Fermi-LAT data
Shang Li, Yun-Feng Liang, Yi-Zhong Fan
Previously, we have shown in Li et al. (2018) that very weak -ray excesses () appear in some Milky Way dwarf spheroidal galaxies (dSphs, including candidates) and the c…
The Highly Self-Absorbed Blazar, PKS\,1351018
Brian Punsly, Sandor Frey, Cormac Reynolds +5
PKS\,1351018 at a redshift of is one of the most luminous, steady synchrotron sources with a luminosity \,erg~s. The synchrotron luminosity does not s…
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…
Fast -ray variability in blazars beyond redsift 3
Shang Li, Zi-Qing Xia, Yun-Feng Liang +2
High-redshift blazars are one of the most powerful monsters in the universe and -ray variability carries crucial information of their relativistic jets. In this work we present…
Testing the dark matter subhalo hypothesis of the gamma-ray source 3FGL J2212.5+0703
Yuan-Peng Wang, Kai-Kai Duan, Peng-Xiong Ma +8
N-body simulations predict that galaxies at the Milky Way scale host a large number of dark matter (DM) subhalos. Some of these subhalos, if they are massive enough or close enough…
3FGL J1924.8-1034 : A Spatially-Extended Stable Unidentified GeV Source?
Zi-Qing Xia, Kai-Kai Duan, Shang Li +8
Milky Way-like galaxies are predicted to host a very large number of dark matter subhalos. Some massive and nearby subhalos could generate detectable gamma-rays, appearing as unide…
Search for gamma-ray emission from eight dwarf spheroidal galaxy candidates discovered in Year Two of Dark Energy Survey with Fermi-LAT data
Shang Li, Yun-Feng Liang, Kai-Kai Duan +7
Very recently the Dark Energy Survey (DES) Collaboration has released their second group of Dwarf spheroidal (dSph) galaxy candidates. With the publicly-available Pass 8 data of Fe…
Discovery of gamma-ray emission from a strongly lobe-dominated quasar 3C 275.1
Neng-Hui Liao, Yu-Liang Xin, Shang Li +7
We systematically analyze the 6-year {\it Fermi}/LAT data of the lobe-dominated quasars (LDQs) in the complete LDQ sample from 3CRR survey and report the discovery of high-energy $…
