Abstract

We show that the absence of the bright optical flashes in most {\it Swift} Gamma-ray Burst (GRB) afterglows can be explained, if the reverse shock region is magnetized with a $\sigma \sim 1$, or the emission spectrum of the electrons accelerated in the mildly magnetized ($0.1<\sigma<1$)> Bibtex entry for this abstract Preferred format for this abstract (see Preferences)
