Parkes observations for project P871 semester 2017APRS_BPSR_01
Fast Radio Bursts (FRBs) are bright, millisecond-duration radio pulses hypothesized to originate at cosmological distances. To date, one FRB has been seen to repeat but their origins remain a puzzling mystery. Some have proposed FRBs come from Crab-like pulsar giant pulses or periods of high activity of distant magnetars. Both mechanisms would gene... morerate observable subsequent FRB-like events. In this proposal we directly test this hypothesis by monitoring the fields of two known FRBs to search for repeating pulses that may explain their progenitors. We target two sources with existing multi-wavelength archival images of the field and small DM-derived distances. less

P871 - A follow-up campaign for fast radio bursts
Within the last few years a brand new type of radio source called a Fast Radio Burst (FRB) was discovered using the Parkes Telescope. FRBs are bright, short radio pulses that appear to only flash once, and only a dozen FRB sources have ever been detected. It is estimated that over 10,000 FRB events are occurring over the whole sky every day! The so... moreurce of FRBs is still a mystery. While some suspect they are cataclysmic events like supernovae in other galaxies, others have proposed that they are giant bursts of emission from flare stars or pulsars. We are in the process of re-observing the locations of known fast radio bursts to search for any repeated pulses to test these predictions. The field of FRB science is still very new, and information on whether FRBs repeat, and how often, is critical to our understanding of these fascinating sources. less
