The Fundamental Plane of GRBs
《Research in Astronomy and Astrophysics》2023年第12期221-229,共9页Xu Zhang Quan-Gui Gao 
partially supported by the Natural Science Foundation of Yunnan Province(grant No.202101AU070006);the Young and Middle-Aged Academic and Technical Reserve Talents of Yunnan Province(202205AC160087)。
Gamma-ray bursts(GRBs)exhibit powerful radiation and relativistic jets similar to blazars.However,the central engine of GRBs remains unknown.In this paper,we use the fundamental plane to analyze a sample of GRBs with ...

Rapid spectroscopy of GRB afterglows is an important and hard task.Based on the archival XSGRB spectral database,we here perform a pilot study on the afterglow's spectroscopy in the forthcoming SVOM era in two aspects...

X-ray and optical plateaus following the main bursts in GRBs and SNe Ⅱ-P: a hint about similar late injection behaviors?
《Research in Astronomy and Astrophysics》2013年第6期671-679,共9页Xiao-Hong Cui Ren-Xin Xu 
supported by the National Basic Research Program of China (973 program, Grant Nos. 2012CB821800 and 2009CB824800);the National Natural Science Foundation of China(Grant Nos. 11225314, 11103026 and 10935001)
We analyze the emission plateaus in the X-ray afterglow light curves of gamma-ray bursts （GRBs） and those in the optical light curves of type Ⅱ plateau su- pernovae （SNe Ⅱ-P） in order to study whether they have ...

Spectral cutoffs of Fermi-LAT GRBs 080916C and 090926A
《Research in Astronomy and Astrophysics》2012年第11期1519-1525,共7页Biao Li Zhuo Li 
supported by the Open Research Program of the Key Laboratory for the Structure and Evolution of Celestial Objects, Chinese Academy of Sciences
It is expected that there should be a spectral cutoff at the high energy end of emission from a prompt gamma-ray burst （GRB）, due to, e.g. γγ absorption and/or a high energy cutoff in the electron distribution. We...

The physical origin of optical flares following GRB 110205A and the nature of the outflow
《Research in Astronomy and Astrophysics》2011年第11期1317-1326,共10页Wei-Hong Gao 
supported by the National Natural Science Foundation of China(Grant No.11073057)
The optical emission of GRB 110205A is distinguished by two flares. We examine two possible scenarios for the optical afterglow emission. In the first scenario, the first optical flare is the reverse shock emission of...

Multiband fitting to three long GRBs with Fermi/LAT data:structured ejecta sweeping up a density-jump medium被引量：1
《Research in Astronomy and Astrophysics》2011年第9期1046-1066,共21页Si-Yi Feng Zi-Gao Dai 
supported by the National Natural Science Foundation of China (Grant Nos. 10873009 and 11033002);the National Basic Research Program of China (973 Program;No. 2007CB815404)
We present broadband （radio, optical, X-ray and GeV） fits to the afterglow light curves and spectra of three long-duration gamma-ray bursts （GRBs 080916C, 090902B, and 090926A） detected by the Gamma-Ray Burst Moni...

Effect of resonant neutrino oscillation on TeV neutrino flavor ratio from choked GRBs
《Research in Astronomy and Astrophysics》2010年第10期943-949,共7页Sarira Sahu Bing Zhang 
supported by DGAPA-UNAM(Mexico) Project No.IN101409;Conacyt project No.103520(SS);supported by NASA NNX09AO94G;NSF AST0908362(BZ)
In the collapsar scenario of the long duration Gamma-Ray Bursts （GRBs）, multi-TeV neutrino emission is predicted as the jet makes its way through the stellar envelope. Such a neutrino signal is also expected for mor...
