On the consistency of the peculiar GRBs 060218 and 060614 with the Ep,i - Eiso correlation

Abstract

We analyze and discuss the position of GRB 060218 and GRB 060614 in the Ep,i - Eiso plane. GRB 060218 is important because of its similarity with GRB 980425, the proto-type event of the GRB-SN connection. While GRB 980425 is an outlier of the Ep,i - Eiso correlation, we find that GRB 060218 is fully consistent with it. This evidence, combined with the `chromatic' behavior of the afterglow light curves, is at odds with the hypothesis that GRB 060218 was a `standard' GRB seen off-axis and supports the existence of a class of truly sub--energetic GRBs. GRB 060614 is a peculiar event not accompanied by a bright Supernova. Based on published spectral information, we find that also this event is consistent with the Ep,i - Eiso correlation. We discuss the implications of our results for the rate of sub--energetic GRBs, the GRB/SN connection and the properties of the newly discovered sub-class of long GRBs not associated with bright Supernovae. We have included in our analysis other recent GRBs with clear evidence (or clear no evidence) of associated SNe.
