The energy requirements of gamma-ray bursts have in past been poorly constrained because of three major uncertainties: the distances to bursts, the degree of burst beaming, and the efficiency of gamma-ray production. The first of these has been resolved, with both indirect evidence (the distribution of bursts in flux and position) and direct evidence (redshifted absorption features in the afterglow spectrum of GRB 970508) pointing to cosmological distances. We now wish to address the second…

Can the Jet Steepen the Light Curves of Gamma-Ray Burst Afterglows?

Beaming of relativistic ejecta in gamma-ray bursts (GRBs) has been postulated by many authors in order to reduce the total GRB energy; thus it is very important to look for the observational evidence

Swift gamma-ray burst afterglows and the forward-shock model

The X-ray light curves of the gamma-ray burst (GRB) afterglows monitored by Swift display one to four phases of power-law decay. In the chronological order they are: the burst tail, the ‘hump’, the

The prompt gamma‐ray emissions and X‐ray afterglows of gamma‐ray burst jets

The distribution of the duration of gamma-ray bursts (GRBs), and the relations of the jet opening angles (theta) to prompt gamma-ray emissions and X-ray afterglow emissions have been investigated

Constraining the Structure of Gamma-Ray Burst Jets through the Afterglow Light Curves

We investigate the effect that the structure of gamma-ray burst (GRB) jets has on the afterglow light curves for observers located at different viewing angles, θobs, from the jet symmetry axis. The


We present multi-wavelength observations and modeling of gamma-ray bursts (GRBs) that exhibit a simultaneous re-brightening in their X-ray and optical light curves, and are also detected at radio

Extended Power-Law Decays in BATSE Gamma-Ray Bursts: Signatures of External Shocks?

The connection between gamma-ray bursts (GRBs) and their afterglows is currently not well understood. Afterglow models of synchrotron emission generated by external shocks in the GRB fireball model

Can all breaks in gamma-ray burst afterglows be explained by jet effects?

Whether gamma-ray bursts are highly beamed or not is a very important question, as it has been pointed out that the beaming will lead to a sharp break in the afterglow light curves during the


The early stages of decelerating gamma-ray burst (GRB) afterglow jets have been notoriously difficult to resolve numerically using two-dimensional hydrodynamical simulations even at very high

The possible ubiquity of energy injection in gamma‐ray burst afterglows

Since its launch in 2004, the Swift satellite has monitored the X-ray afterglows of several hundred gamma-ray bursts (GRBs), and revealed that their X-ray light curves are more complex than

Gamma-Ray Burst Afterglows from Anisotropic Jets

Some progenitor models of gamma-ray bursts (GRBs; e.g., collapsars) may produce anisotropic jets in which the energy per unit solid angle is a power-law function of the angle (∝θ-k). We calculate



How to Tell a Jet from a Balloon: A Proposed Test for Beaming in Gamma-Ray Bursts

If gamma-ray bursts are highly collimated, radiating into only a small fraction of the sky, the energy requirements of each event may be reduced by several (~4-6) orders of magnitude, and the event

Hydrodynamics of Gamma-Ray Burst Afterglow

The detection of delayed emission at X-ray optical and radio wavelengths (“afterglow”) following gamma-ray bursts (GRBs) suggests that the relativistic shell that emitted the initial GRB as the

The Soft X-Ray Afterglow of Gamma-Ray Bursts, A Stringent Test for the Fireball Model

I consider the recent discovery of a soft X-ray source inside the error box of the gamma-ray burst GB 960720 by the SAX, ASCA, and ROSAT satellites, in terms of the fireball model. I show that the

γ-Ray Burst Afterglow: Confirming the Cosmological Fireball Model

The recent detection of delayed X-ray and optical emission—“afterglow”—associated with γ-ray bursts (GRBs) supports models in which the bursts are produced by relativistic expanding blast

The afterglow, redshift and extreme energetics of the γ-ray burst of 23 January 1999

Long-lived emission, known as afterglow, has now been detected from about a dozen γ-ray bursts. Distance determinations place the bursts at cosmological distances, with redshifts, z, ranging from ∼1

The radio afterglow from the γ-ray burst of 8 May 1997

Important insight into the nature of γ-ray bursts (GRBs) has been gained in recent months mainly due to the immediate, precise localization of the bursts and the discovery of relatively long-lived

Multiwavelength Afterglows in Gamma-Ray Bursts: Refreshed Shock and Jet Effects

We present an analytical approach to calculate the hydrodynamics of the interaction between a relativistic ejecta and a surrounding medium, whose evolution serves as a model for gamma-ray burst (GRB)

The afterglow, the redshift, and the extreme energetics of the gamma-ray burst 990123

Afterglow, or long-lived emission, has now been detected from about a dozen well-positioned gamma-ray bursts. Distance determinations made by measuring optical emission lines from the host galaxy, or

Shocked by GRB 970228: the afterglow of a cosmological fireball

The location accuracy of the BeppoSAX Wide Field Cameras and acute ground-based follow-up have led to the detection of a decaying afterglow in X-rays and optical light following the classical

Optical and Long-Wavelength Afterglow from Gamma-Ray Bursts

We discuss the evolution of cosmological gamma-ray burst remnants, consisting of the cooling and expanding fireball ejecta together with any swept-up external matter, after the gamma-ray event. We
