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 compare theoretical models with afterglow observations, we calculate here the broadband spectrum and corresponding light curve of synchrotron radiation from a power-law distribution of electrons in an expanding relativistic shock. Both the spectrum and the light curve consist of several power-law… Expand

Spectra of gamma-ray burst afterglows
Gamma-ray burst afterglows are believed to be described reasonably by synchrotron emission from relativistic blast waves at cosmological distances. We perform a detailed calculation using a fullExpand

Light Curves of Gamma-Ray Burst Optical Flashes
The standard model of gamma-ray burst (GRB) afterglows assumes that relativistically expanding material is decelerating as a result of interaction with the surrounding medium. The afterglows are wellExpand

We present gamma-ray burst afterglow light curves in X-ray, optical and radio bands for various distributions of accelerated electrons behind the shock. The effects of lateral expansion of the jetExpand
Gamma-ray burst afterglow scaling coefficients for general density profiles
Gamma-ray burst (GRB) afterglows are well described by synchrotron emission originating from the interaction between a relativistic blast wave and the external medium surrounding the GRB progenitor.Expand
The Shape of Spectral Breaks in Gamma-Ray Burst Afterglows
Gamma-ray burst afterglows are well described by synchrotron emission from relativistic blast waves expanding into an external medium. The blast wave is believed to amplify the magnetic field andExpand
Gamma‐ray bursts: optical afterglows in the deep Newtonian phase
Gamma-ray burst remnants become trans-relativistic typically in days to tens of days, and they enter the deep Newtonian phase in tens of days to months, during which the majority of shock-acceleratedExpand
Temporal Evolution of the Gamma-ray Burst Afterglow Spectrum for an Observer: GeV--TeV Synchrotron Self-Compton Light Curve
We numerically simulate the gamma-ray burst (GRB) afterglow emission with a one-zone time-dependent code. The temporal evolutions of the decelerating shocked shell and energy distributions ofExpand
