This is the first clear evidence that long-duration gamma-ray bursts can be either associated with supernovas which do not have [the usual] properties or they can be produced by a different phenomenon," note Massimo Della Valle of the INAF-Astrophysical Observatory of Arcetri in Firenze, Italy, and his colleagues.
