Measuring the beaming angle of GRB 030329 by fitting the rebrightenings in its multiband afterglow被引量：1
《Research in Astronomy and Astrophysics》2010年第11期1119-1126,共8页Wei Deng Yong-Feng Huang Si-Wei Kong 
supported by the National Natural Science Foundation of China(Grant Nos.10625313 and 11033002);the National Basic Research Program of China(973 Program,Grant No.2009CB824800)
Multiple rebrightenings have been observed in the multiband afterglow of GRB 030329. In particular, a marked and quick rebrightening occurred at about t 1.2 × 10^5 s. Energy injection from late and slow shells seems ...

Modeling the radio and optical/NIR afterglows of GRB 980703:A numerical study
《Science China(Physics,Mechanics & Astronomy)》2009年第12期2047-2053,共7页CHENG KwongSang 
Supported by the National Natural Science Foundation of China (Grant Nos. 10625313 and 10973039);the National Basic Research Program of China (Grant No. 2009CB824800);a GRF Grant of Hong Kong Government (Grant No. HKU701109P)
Extensive multi-band afterglow data are available for GRB 980703. Especially,its radio afterglow was very bright and was monitored until more than 1000 days after the trigger time. Additionally,there is no obvious spe...

Long-term continuous energy injection in the afterglow of GRB 060729
《Research in Astronomy and Astrophysics》2009年第12期1317-1323,共7页Ming Xu Yong-Feng Huang Tan Lu 
supported by the National Natural Science Foundation of China (Grant Nos.10625313 and 10473023);the National Basic Research Program of China (973 Program,Grant No.2009CB824800)
A long plateau phase and an amazing level of brightness have been observed in the X-ray afterglow of GRB 060729. This peculiar light curve is likely due to longterm energy injection in external shock. Here, we present...

Ring-Shaped Jets in Gamma-Ray Bursts
《Chinese Journal of Astronomy and Astrophysics》2008年第4期411-420,共10页Ming Xu Yong-Feng Huang Si-Wei Kong 
the National Natural Science Foundation of China(Grants 10625313 and 10221001)
When the axis of a gamma-ray burst （GRB） does not coincide with the spin axis of its source, there may result a ring-shaped jet. Using some refined jet dynamics, we calculate multi-wavelength afterglow light curves ...

Nonrelativistic phase in γ-ray burst afterglows
《Progress in Natural Science:Materials International》2007年第11期1261-1270,共10页Huang Yongfeng Lu Tan Cheng Kwongsang 
Supported by National Natural Science Foundation of China (Grant Nos 10625313 ,10221001 ,10473023) ;the RGC grant of the Hong Kong Government under HKU7014/04P
The discovery of multiband afterglows definitely shows that most γ-ray bursts are of cosmological origin. γ-ray bursts are found to be one of the most violent explosive phenomena in the Universe, in which astonishin...
