Detection of GeV -ray emission in the direction of HESS J1731-347 with Fermi-LAT
Xiao-Lei Guo, Yu-Liang Xin, Neng-Hui Liao +3
We report the detection of GeV -ray emission from supernova remnant HESS J1731-347 using 9 years of {\it Fermi} Large Area Telescope data. We find a slightly extended GeV source…
GW170817/GRB 170817A/AT2017gfo association: some implications for physics and astrophysics
Hao Wang, Fu-Wen Zhang, Yuan-Zhu Wang +9
On 17 August 2017, a gravitational wave event (GW170817) and an associated short gamma-ray burst (GRB 170817A) from a binary neutron star merger had been detected. The followup opt…
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…
The flat-spectrum radio quasar 3C 345 from the high to the low emission state
M. Berton, N. H. Liao, G. La Mura +17
We report simultaneous observations at different energy bands in radio, optical, UV, X-rays and rays of the flat-spectrum radio-quasar 3C 345. We built the light curve of the s…
Two transient X-ray Quasi-Periodic Oscillations separated by an intermediate state in 1H 0707-495
Peng-Fei Zhang, Peng Zhang, Neng-Hui Liao +3
In the narrow-line Seyfert 1 galaxy 1H 0707-495, recently a transient quasi-periodic oscillation (QPO) signal with a frequency of Hz has been detected at a…
The SNR Puppis A Revisited with Seven Years of Fermi Large Area Telescope Observations
Yu-Liang Xin, Xiao-Lei Guo, Neng-Hui Liao +3
Puppis A is a very famous and extensively studied supernova remnant (SNR) that shows strong evidence of shock-cloud interaction. We re-analyze the GeV -ray emission of it using…
Possible Quasi-Periodic modulation in the z = 1.1 -ray blazar PKS 0426-380
Pengfei Zhang, Dahai Yan, Nenghui Liao +3
We search for -ray and optical periodic modulations in a distant flat spectrum radio quasar (FSRQ) PKS 0426-380 (the redshift ). Using two techniques (i.e., the maximum l…
