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…
Neutron star-black hole coalescence rate inferred from macronova/kilonova observations
Xiang Li, Yi-Ming Hu, Zhi-Ping Jin +2
Neutron starblack hole (NSBH) coalescences are widely believed to be promising gravitational wave sources in the era of advanced detectors of LIGO/Virgo but such binaries hav…
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…
Evaluating the bulk Lorentz factors of outflow material: lessons learned from the extremely-energetic outburst GRB 160625B
Yuan-Zhu Wang, Hao Wang, Shuai Zhang +6
GRB 160625B is an extremely-bright outburst with well-monitored afterglow emission. The geometry-corrected energy is high up to erg or even $\sim 8\times 10…
Possible dark matter annihilation signal in the AMS-02 antiproton data
Ming-Yang Cui, Qiang Yuan, Yue-Lin Sming Tsai +1
Using the latest AMS-02 cosmic ray antiproton flux data, we search for potential dark matter annihilation signal. The background parameters about the propagation, source injection,…
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…
Search for gamma-ray line features from Milky Way satellites with Fermi-LAT Pass 8 data
Yun-Feng Liang, Zi-Qing Xia, Zhao-Qiang Shen +7
With 91 months of the publicly available Fermi-LAT Pass 8 data, we analyze the gamma-ray emission from the Milky Way satellites to search for potential line signals due to the anni…
Interpretations of the possible 42.7 GeV -ray line
Lei Feng, Yun-Feng Liang, Tie-Kuang Dong +1
Recently Liang et al. found a tentative line signal at about 43 GeV in the directions of sixteen nearby Galaxy Clusters. If arising from dark matter annihilation, the mass of the d…
-ray emission signals in the massive graviton mediated dark matter model
Cun Zhang, Ming-Yang Cui, Lei Feng +2
Dark matter may interact with Standard Model (SM) particle through the exchange of a massive spin-2 graviton producing signals that can be detected. In this work we examine the …
Discovery of -ray emission from the radio-intermediate quasar III Zw 2: violent jet activity with intraday -ray variability
Neng-Hui Liao, Yu-Liang Xin, Xu-Liang Fan +4
III Zw 2 is the prototype of radio-intermediate quasars. Although there is the evidence of possessing strong jet, significant -ray emission has not been reported before. In this…
The Macronova in GRB 050709 and the GRB/macronova connection
Zhi-Ping Jin, Kenta Hotokezaka, Xiang Li +6
GRB 050709 was the first short Gamma-ray Burst (sGRB) with an identified optical afterglow. In this work we report a re-analysis of the publicly available data of this event and th…
Search for a gamma-ray line feature from a group of nearby Galaxy clusters with Fermi LAT Pass 8 data
Yun-Feng Liang, Zhao-Qiang Shen, Xiang Li +6
Galaxy clusters are the largest gravitationally bound objects in the universe and may be suitable targets for indirect dark matter searches. With 85 months of Fermi-LAT Pass 8 publ…
Implications of the Tentative Association between GW150914 and a {\it Fermi}-GBM Transient
Xiang Li, Fu-Wen Zhang, Qiang Yuan +4
The merger-driven Gamma-ray Bursts (GRBs) and their associated gravitational wave (GW) radiation, if both successfully detected, have some far-reaching implications, including for…
GRB/GW association: Long-short GRB candidates, time-lag, measuring gravitational wave velocity and testing Einstein's equivalence principle
Xiang Li, Yi-Ming Hu, Yi-Zhong Fan +1
Short-duration gamma-ray bursts (SGRBs) are widely believed to be powered by the mergers of compact binaries, such as binary neutron stars or possibly neutron star-black hole binar…
