Estimating the peak energy of Swift gamma-ray bursts using supervised machine learning
Wan-Peng Sun, Si-Yuan Zhu, Da-Ling Ma +1
Gamma-ray bursts (GRBs) are among the most energetic explosive phenomena in the Universe, and their peak energy () is a key physical quantity for understanding the promp…
Unveiling the spectral morphological division of fast radio bursts with CHIME/FRB Catalog 2
Wan-Peng Sun, Yin-Long Cao, Yong-Kun Zhang +7
Fast radio bursts (FRBs) are commonly classified into repeating and apparently nonrepeating sources, yet whether this distinction reflects intrinsically different physical populati…
Late afterglow emission statistics: a clear link between GW170817 and bright short GRBs
Kai-Kai Duan, Zhi-Ping Jin, Fu-Wen Zhang +4
GW170817, the first neutron star merger event detected by advanced LIGO/Virgo detectors, was associated with an underluminous short duration GRB 170817A. In this work we compare th…
GW170817: The energy extraction process of the off-axis relativistic outflow and the constraint on the equation of state of neutron stars
Yuan-Zhu Wang, Dong-Sheng Shao, Jin-Liang Jiang +6
As revealed recently by the modeling of the multi-wavelength data of the emission following GW170817/GRB 170817A, there was an off-axis energetic relativistic outflow component lau…
How Special Is GRB 170817A?
Chuan Yue, Qian Hu, Fu-Wen Zhang +5
GRB 170817A is the first short gamma-ray burst (GRB) with direct detection of the gravitational-wave radiation and also the spectroscopically identified macronova emission (i.e., A…
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…
