熵缩放指数可以用来量度伽玛暴光变的复杂性。对目前已知红移的78个暴的光变进行统计分析发现,这个缩放指数与伽玛暴的光度和谱的峰值能量两两相关,对这三个物理量进行偏相关分析发现,缩放指数和谱的峰值能量之间没有相关性,且在这两者...

Duration distributions for different softness groups of gamma-ray bursts被引量：1
《Science China(Physics,Mechanics & Astronomy)》2010年第7期1375-1382,共8页GUPTA A.C. 
supported in part by the National Natural Science Foundation of China (Grant Nos. 10633010,10573005 and 10747001);the National Basic Research Program of China (Grant No. 2007CB815405);the financial support from the Guangzhou Education Bureau and Guangzhou Science and Technology Bureau
Gamma-ray bursts(GRBs) are divided into two classes according to their durations.We investigate if the softness of bursts plays a role in the conventional classification of the objects.We employ the BATSE(Burst and Tr...

The flux-E_p relation within GRB060218 in comparison with typical GRB pulses被引量：3
《Science China(Physics,Mechanics & Astronomy)》2010年第S1期78-81,共4页DONG Wei,LIANG EnWei & LU RuiJing Physical Science & Technology College,Guangxi University,Nanning 530004,China 
supported by the National Basic Research Program of China (Grant No. 2009CB824800);the National Natural Science Foundation of China (Grant Nos. 10873002 and 10747001);Guangxi SHI-BAI-QIAN Project (Grant No. 2007201);the Program for 100 Young and Middle-aged Disciplinary Leaders in Guangxi Higher Education Institutions,and the Research Foundation of Guangxi University (Grant No. M30520)
The prompt gamma-ray/X-ray emission of gamma-ray burst(GRB) 060218 was simultaneously observed by the Burst Alert Telescope(BAT) and X-ray Telescope(XRT) onboard Swift.Its peak energy of the joint νfν spectrum(Ep) c...

Luminosity-peak energy relation in the decay phases of gamma-ray burst pulses被引量：1
《Science China(Physics,Mechanics & Astronomy)》2010年第1期163-170,共8页LU RuiJing & LIANG EnWei Physical Science & Technology College, Guangxi University, Nanning 530004, China 
supported by the National Natural Science Foundation of China (Grant Nos.10747001, 10873002, and 10847003);the National Basic Research Program of China (Grant No. 2009CB824800), and the Research Foundation of Guangxi University (Grant No. M30520)
Using time-resolved spectral data for a sample of 30 pulses in 27 bright GRBs detected with CGRO/BATSE, we investigate the luminosity-peak energy relation (L-E p relation) in the decay phases of these pulses. A tight ...

A cosmological model with negative energy photons
《Chinese Physics B》2010年第1期606-610,共5页覃一平 
Project supported by the National Natural Science Foundation of China (Grant Nos. 10573005, 10633010 and 10747001)
According to recent investigations of states of quantum fields, we postulate that there exist negative energy photons in the universe. With this assumption, we find a solution of Einstein＇s equation without introduci...

Development of the spectrum of gamma-ray burst pulses influenced by the intrinsic spectral evolution and the curvature effect
《Chinese Physics B》2009年第2期825-844,共20页覃一平 
supported by the National Natural Science Foundation of China (Grant Nos 10573005 and 10747001)
The spectral evolution of gamma-ray burst pulses assumed to arise from the emission of fireballs is explored. It is found that due to the curvature effect, the integrated flux is well related to peak energy by a power...
