Parkes observations for project P958 semester 2019APRS_72
Fast radio bursts (FRBs) continue to raise more questions than they answer. Until a few months ago, only one burst – the only one known to repeat - had been localized to a bright radio nebula (either a young supernova remnant or pulsar wind nebulae) in a distant dwarf galaxy.
Over the last year searches with the Australian Square Kilomet... morere Array Pathfinder (ASKAP) have detected 28 bursts, two of which have been localised to host galaxies at redshifts > 0.3. These bursts and their hosts are very unlike the repeater, suggesting there may be a dichotomy in the population. Over the next six months we expect to detect another 12 FRBs, which will also have sub-arcsecond localisations. Here we propose to search this population for repeats. 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, will either confirm the presence of additional repeating FRBs or the uniqueness of FRB 121102 amongst the population. less

P958 - Searching for repetition from ASKAP fast radio bursts
Fast radio bursts are brilliant flashes of radio emission that outshine most other sources in the sky for the blink of they eye that they are seen. Because of their short duration, it has been hard to tell where they come from and what causes them. Recently one has been found to repeat (making it much easier to study), and it comes from a very dist... moreant galaxy (billions of light years away). To better understand the bursts, we are conducting a survey with the Australian Square Kilometre Array Pathfinder in Western Australia to more than double the known objects. We are using the Parkes telescope to see if any of the new bursts repeat. less
