Analysis of the peculiar GRB 141221A

Abstract

We investigate the properties of GRB 141221A in different wavelengths. This long GRB shows different faces at different epochs and wavelengths such as a rise at optical wavelength that we can not see in X-ray. The visible/IR light-curves decay is sharpening at the time when the X-ray flare reaches a maximum. We discuss it in the light of alternative models of GRBs.
