Relativistic ejecta from X-ray flash XRF 060218 and the rate of cosmic explosions
Article Abstract:
Radio and X-ray observations of the second-nearest gamma-ray burst (GRB) X-ray flash XRF 060218 associated with supernova SN 2006aj are reported, which reveal that this XRF is a hundred times less energetic but ten times more common than cosmological GRBs. An energy release of [10.sup.48] erg and presence of relativistic ejecta, combined with a black hole or magnetar accretion-fed, rapidly rotating compact source of central engine, distinguish XRF 060218 from ordinary supernovae.

A common origin for cosmic explosions inferred from calorimetry of GRB030329
Article Abstract:
The radio observation of GRB030329 that undertakes calorimetry of the explosion is reported. Given the firm link of GRB030329 with SN2003dh, results indicate a common origin for cosmic explosions in which the energy in the highest-velocity ejecta is extremely variable.
