Blasts from the radio heavens
Article Abstract:
A transient radio source with unique properties is discovered close to the centre of the Galaxy whose powerful radio bursts, clock-like regularity and unusual timescale imply a temperature greater than trillions of degrees. This high temperature implies that the radiation emitted from all parts of the radio source is coherent which means that it is almost entirely of a single wavelength.

The afterglow and elliptical host galaxy of the short gamma-ray burst GRB 050724
Article Abstract:
The discovery of the first radio afterglow from the short burst GRB 050724, which unambiguously associates it with an elliptical galaxy at a redshift z=0.257 is reported. The nature of the host galaxy demonstrates that short GRBs arise from an old stellar population, strengthening earlier suggestions and providing support for colescing compact object binaries as the progenitors.

A photometric redshift of z = 6.39 plusmn 0.12 for GRB 050904
Article Abstract:
A study on the discovery of the bright near-infrared afterglow of gamma-ray burst (GRB) 050904 is reported. The photometric shift of the burst is measured to be z=6.39 plusmn 0.12 and the results demonstrate that GRBs can be used to trace the star formation, metallicity, and reionization histories of the early Universe.
