Scientific paper

For Southern Hemisphere GRBs, the ATCA can be used to carry out a long-term follow-up radio observations program for GRB afterglows. We propose a continuation of our GRB radio-afterglow detection and monitoring survey of the southern sky, consisting of bi-monthly observations of a selected sample of newly discovered GRBs. Our recent GRB observations and the success of our data analysis strategy indicates it as a feasible and promising project. The primary goal of this program is to select targets for high-resolution and high sensitivity observations using the new e-VLBI capability of the LBA, for measurements of the structures, velocities, sizes, evolution and energetics of the radio counterparts of these sources. Goals of the ATCA project include: (1) obtaining information on GRBs at declinations that cannot be reached by the VLA, so complementing Northern Hemisphere surveys; (2) increasing the number of these sources for radio follow-up so as to improve our chances of finding the radio counterparts of interesting objects such as low-redshift, short-duration GRBs. This program will pave the way for coordinated transient science with the new e-VLBI capabilities of the LBA, the broadband ATCA and ASKAP
