Fast radio bursts (FRBs) continue to raise more questions than they answer. Until last year, only one burst – the only one known to repeat - had been localized to a bright radio nebula (either a youn... moreg supernova remnant or pulsar wind nebulae) in a distant dwarf galaxy. Over the last two year searches with the Australian Square Kilometre Array Pathfinder (ASKAP) have detected 31 bursts, five of which have been localised to host galaxies at redshifts ranging from 0.1 to 0.5. These bursts and their hosts are very unlike the repeater, suggesting there may be a dichotomy in the population. However one of the arcminute-localised ASKAP FRBs has recently been found to repeat. Here we propose to search and study repetitions in this FRB population. Our comprehensive sample and a dense monitoring campaign of well localised bursts, at a fluence limit more than 60 times lower than that of their detections to characterise the fraction of bursts that repeat. For bursts that repeat the unique wide bandwidth observations will be used to test leading models of burst emission.less

This collection contains two spectral image cubes of the LGG 351 group. The image cubes consist of 23 ASKAP beams and 7 MHz of bandwidth (1396.57 to 1403.56 MHz, with a resolution of 18.5 kHz). The sk... morey coverage is 13:24:00 < RA < 13:38:00 and -26:30:00 < DEC < -33:30:00. One of the spectral cubes has 45"x35" synthesized beam, which is used in For et al. 2019, MNRAS DOI: 10.1093/mnras/stz2501 . The other spectral cube has synthesized beam of 26"x19". less
