When GRB afterglows get softer, hard components come into play
When GRB afterglows get softer, hard components come into play
We investigated the ability of simple spectral models to describe the early afterglow emission of GRBs. We found that four spectra, belonging to the GRB060502A, GRB060729, GRB060904B, GRB061H0A prompt–afterglow transition phase, can be modeled neither by a single power–law nor by the Band model. Instead we find that the data …
