What SWIFT has Taught us about X-ray Flashes and Long-duration Gamma-Ray Bursts

A. de Rújula

Abstract

Recent data gathered and triggered by the SWIFT satellite have greatly
improved our knowledge of long-duration gamma ray bursts (GRBs) and
X-ray flashes (XRFs). This is particularly the case for the X-ray data
at all times, and for UV and optical data at very early times. I show
that the optical and X-ray observations are in excellent agreement with
the predictions of the ``cannonball" model of GRBs and XRFs. Elementary
physics and just two mechanisms underlie these predictions: inverse
Compton scattering and synchrotron radiation, generally dominant at
early and late times, respectively. I put this result in its proper
context and dedicate the paper to those who planned, built and operate
SWIFT, a true flying jewel.
