The Dust Scattering Model Can Not Explain The Shallow X-ray Decay in GRB Afterglows
Rong-Feng Shen, Richard Willingale, Pawan Kumar +2
A dust scattering model was recently proposed to explain the shallow X-ray decay (plateau) observed prevalently in Gamma-Ray Burst (GRB) early afterglows. In this model the plateau…
Scattered Emission from A Relativistic Outflow and Its Application to Gamma-Ray Bursts
R. -F. Shen, R. Barniol Duran, P. Kumar
We investigate a scenario of photons scattering by electrons within a relativistic outflow. The outflow is composed of discrete shells with different speeds. One shell emits radiat…
No Universality for Electron's Power-Law Index (p) in Gamma-Ray Bursts and Other Relativistic Sources
R. -F. Shen, P. Kumar, E. L. Robinson
The Gamma-Ray Burst (GRB) prompt emission is believed to be from highly relativistic electrons accelerated in relativistic shocks. From the GRB high-energy power-law spectral indic…
Spectral lags and the energy dependence of pulse width in gamma-ray bursts: contributions from the relativistic curvature effect
R. -F. Shen, L. -M. Song, Z. Li
We compute the temporal profiles of the gamma-ray burst pulse in the four Burst and Transient Source Experiment (BATSE) Large Area Detector (LAD) discriminator energy channels, wit…
The Power Spectra of Two Classes of Long-duration Gamma-ray Bursts
R. F. Shen, L. M. Song
We have studied the averaged power density spectra (PDSs) of two classes of long-duration gamma-ray bursts in the recent classification by Balastegui et al.(2001) based on neural n…
Characteristic Variability Time Scales of Long Gamma-Ray Bursts
R. F. Shen, L. M. Song
We determined the characteristic variability time scales (Δt_p) of 410 bright and long GRBs, by locating the peaks of their Power Density Spectra, defined and calculated in the tim…
