In recent years, increasing evidence has emerged for a thermal component in the γ-and X-
ray spectrum of the prompt emission phase in gamma-ray bursts. The temperature and flux …

We present a detailed analysis on the spectral lags of the short gamma-ray bursts (GRBs)
and compare them with that of the long GRBs by using the CGRO (Compton Gamma-ray …

Context. The joint X-ray and gamma-ray observations of GRB 090618 by very many
satellites offer an unprecedented possibility of testing crucial aspects of theoretical models …

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 …

ABSTRACT A time-resolved spectral analysis for a sample of 22 intense, broad gamma-ray
burst (GRB) pulses from the Compton Gamma Ray Observatory (CGRO)/BATSE GRB …

ABSTRACT A study of a set of well-isolated pulses in long and intermediate gamma-ray
burst (GRB) light curves indicates that simple pulse models having smooth and monotonic …

We present time-resolved spectral analysis of the steep decay segments of 29 bright X-ray
flares of gamma-ray bursts (GRBs) observed with the Swift/X-ray telescope, and model their …

In this paper we derive in great detail the formula for count rates of gamma-ray bursts
(GRBs) in the framework of fireballs, in terms of the integral of time, where the Doppler effect …

Recently, Shen et al. have studied the contributions of the curvature effect of fireballs to the
spectral lag and have shown that the observed lags can be accounted for by the effect. Here …

We introduce a simple model to explain the time-reversed and stretched residuals in gamma-
ray burst (GRB) pulse light curves. In this model an impactor wave in an expanding GRB jet …
