Is GRB 100418A a Cosmic Twin of GRB 060614?

摘要：

GRB 100418A is a long burst at z=0.624 without detection of associated supernova (SN). We present a detailed analysis on this event and discuss possible origins of its multi-wavelength emission. The temporal features of this event is similar to GRB 060614, a well-known nearby long GRB without SN association (possibly a Type I GRB), indicating that the two events may be cosmic twins. However, both the circum-burst medium density and the GRB classification based on the gamma-ray energy and spectrum suggest that GRB 100418 A would be a Type Ⅱ GRB. These results make a great puzzle on the progenitors of this kind of events, if they belong to the same population.
