Research Abstract

Actually, on December 2009, we made the mosaicing VLBI observation for 4 radio transients which were already reported. In this observation, the progenitors of 4 radio transients couldn't be identified, but we could confirm that no radio sources whose flux densities exceed 150 mJy at 8 GHz (signal to noise ratio of 8) are exits. And we could also confirm to be sensitive enough to carry out the follow-up observation for radio transients with the VLBI
