Long gamma-ray bursts without visible supernovae: a case study of redshift estimators and alleged novel objects.

DADO S., DAR A., DE RUJULA A. and PLAGA R.

Abstract (from CDS):

It has been argued that the observational limits on a supernova (SN) associated with GRB 060614 convincingly exclude a SN akin to SN 1998bw as its originator and provide evidence for a new class of long-duration GRBs. We discuss this issue in the contexts of indirect ``redshift estimators'' and of the fireball and cannonball models of GRBs. The latter explains the unusual properties of GRB 060614: at its debated but favored low redshift (0.125), they are predicted, as opposed to exceptional, if the associated core-collapse SN is of a recently discovered, very faint type. We take the occasion to discuss the association between GRBs and SNe.
