In gamma-ray burst research, it is quite common to fit the afterglow light curves with a broken power law to interpret the data. We apply this method to a computer-simulated population of afterglows and find systematic differences between the known model parameters of the population and the ones derived from the power-law fits. In general, the slope of the electron energy distribution is overestimated from the prebreak light curve slope while being underestimated from the postbreak slope. We…

Testing the blast wave model with Swift GRBs
The complex structure of the light curves of Swift Gamma-Ray Bursts (GRBs) has made the identification of breaks, and the interpretation of the blast wave caused by the burst, more difficult than in
Are the missing X-ray breaks in gamma-ray burst afterglow light curves merely hidden?
Gamma-ray burst (GRB) afterglow observations in the Swift era have a perceived lack of achromatic jet breaks compared to the BeppoSAX or pre-Swift era. Specifically, relatively few breaks, consistent
Luminosity functions of gamma-ray burst afterglows
Aims. Use the standard fireball model to create virtual populations of gamma-ray burst afterglows and study their luminosity functions. Methods. We randomly vary the parameters of the standard
Jet simulations and gamma-ray burst afterglow jet breaks
The conventional derivation of the gamma-ray burst afterglow jet break time uses only the blast wave fluid Lorentz factor and therefore leads to an achromatic break. We show that in general gamma-ray

Constraining the energy budget of GRB 080721
The energy constraint can be used as an observational input for models of the progenitors of long GRBs: it is discussed how such high collimation-corrected energies could be accommodated with certain parameters of the standard massive star core-collapse models.
Energy Injection in Gamma-Ray Burst Afterglow Models
We extend the standard fireball model, widely used to interpret gamma-ray burst (GRB) afterglow light curves, to include energy injections and apply the model to the afterglow light curves of GRB
Off-axis Gamma-ray Burst Afterglow Modeling Based on a Two-dimensional Axisymmetric Hydrodynamics Simulation
Starting as highly relativistic collimated jets, gamma-ray burst outflows gradually slow down and become nonrelativistic spherical blast waves. Although detailed analytical solutions describing the

Gamma-Ray Burst Afterglow Light Curves in the Pre-Swift Era: A Statistical Study
We present the results of a systematic analysis of the world sample of optical/near-infrared afterglow light curves observed in the pre-Swift era by the end of 2004. After selecting the best observed
Spectra and light curves of gamma-ray burst afterglows
The recently discovered gamma-ray burst afterglow is believed to be described reasonably well by synchrotron emission from a decelerating relativistic shell that collides with an external medium. To
Afterglow light curves, viewing angle and the jet structure of γ-ray bursts
Gamma-ray bursts are often modelled as jet-like outflows directed towards the observer; the cone angle of the jet is then commonly inferred from the time at which there is a steepening in the
The Dynamics and Light Curves of Beamed Gamma-Ray Burst Afterglows
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
The Collimation-corrected Gamma-Ray Burst Energies Correlate with the Peak Energy of Their νFν Spectrum
We consider all bursts with known redshift and νFν peak energy, E. For a good fraction of them an estimate of the jet opening angle is available from the achromatic break of their afterglow light
We present a comprehensive sample of all gamma-ray burst (GRB) afterglows with known distances, and we derive their conical opening angles based on observed broadband breaks in their light curves.
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

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 use of gamma-ray burst (GRB) energetics for cosmography has long been advanced as a means to probe out to high redshifts, to the epoch of deceleration. However, although relatively immune to
Exact versus Approximate Solutions in Gamma-Ray Burst Afterglows
We have recently obtained the exact analytic solutions for the relativistic equations relating the radial and time coordinates of a relativistic, thin uniform shell expanding in the interstellar
