Delayed Afterglow Onset Interpreted as Baryon-Poor Viewing Angle

Abstract

We have suggested previously that baryons in GRB fireballs infiltrate from the surrounding walls that collimate the fireball. The efficiency ${\epsilon }_b$ for generating blast energy can then be angle dependent. Delayed onset of afterglow can be interpreted as being due to a baryon-poor viewing angle.
