Observational Signatures of High-Energy Emission during the Shallow Decay Phase of GRB X-Ray Afterglows
Y. W. Yu, X. W. Liu, Z. G. Dai
The widely existing shallow decay phase of the X-ray afterglows of gamma-ray bursts (GRBs) is generally accepted to be due to long-lasting energy injection. The outflows carrying t…
High Efficiency of Gamma-Ray Bursts Revisited
Y. C. Zou, Z. G. Dai
Using the conservation of energy and momentum during collisions of any two shells, we consider the efficiency of gamma-ray bursts by assuming that the ejecta from the central engin…
Constraints on Dark Energy Models Including Gamma Ray Bursts
Hong Li, Meng Su, Zuhui Fan +2
In this paper we analyze the constraints on the property of dark energy from cosmological observations. Together with SNe Ia Gold sample, WMAP, SDSS and 2dFGRS data, we include 69…
Emission Processes of High Energy Gamma Rays from Gamma-Ray Bursts
X. Y. Wang, Z. G. Dai, T. Lu
Synchrotron self-Compton (SSC) process in the reverse shocks of gamma-ray bursts is suggested to be responsible for the observed prompt high-energy gamma-ray emissions from several…
Accretion-Induced Conversion of High-Velocity Neutron Stars to Strange Stars in Supernovae and Implications for Gamma-Ray Bursts
K. S. Cheng, Z. G. Dai
We present a new model for gamma-ray bursts (GRBs) that are not only associated with supernovae but also have small baryon contamination. In this model, we assume a newborn neutron…
Energy Sources of Soft Gamma-Ray Repeaters
K. S. Cheng, Z. G. Dai
Quiescence and burst emission and relativistic particle winds of soft gamma-ray repeaters (SGRs) have been widely interpreted to result from ultrastrongly magnetized neutron stars.…
