Parkes observations for project P892 semester 2016OCTS_BPSR_40
SUPERBx is an extension to the SUPERB survey which looks at the highest Galactic latitudes in a search for fast radio bursts (FRBs). Our most recent results show that there is a strong Galactic latitude dependence to FRB detectability with the detection rate being 4 times higher ~45 degrees and higher above the plane; this is where SUPERBx will foc... moreus its efforts from now on. SUPERBx uses optimised GPU codes to search for pulsars and fast radio bursts (FRBs), making discoveries in real time. Handling our data as it comes in is essential for the SKA Phase I era so this work applies directly to the high-data rates of next generation telescopes. The FRBs discovered (we have already discovered four FRBs in this project) will have much more associated information than all previous detections. Firstly our discovery lag is ~1 second, rather than months/years. The Parkes observations will be shadowed by other radio telescopes (in particular the refurbished Molonglo which has now reached a level of performance where it has independently discovered 3 FRBs in 2016) to allow localisation of the discovered FRBs, and a host of optical and high-energy telescopes will then be triggered as appropriate. This is key for identifying FRB host galaxies, so as to solve the mystery of their progenitors and to exploit their many uses as tools for precision cosmology measurements. less

P892 - SUPERBx - The SUrvey for Pulsars & Extragalactic Radio Bursts Extension
We are surveying the sky to find fast radio bursts (FRBs). FRBs originate from outside of our Galaxy, and are about a million times more distant than the pulsars that Parkes often studies. FRBs are one-off flashes of radio light, only recently discovered. Unlike pulsars we do not know what causes FRBs. A leading theory is that they are the bangs yo... moreu get when an unstable pulsar collapses to a black hole. We will identify FRBs with Parkes and and other radio telescopes (Molonglo - which is 300 km from Parkes, the GMRT in India and the MWA in Western Australia). Using multiple telescopes together will enable us to zoom-in on the FRB region much better than ever before so that we can finally pinpoint the galaxies in which they occur, and solve this mystery once and for all. To make our discoveries in real time, i.e. 'live', we will perform very complex computing using super-fast GPUs, aka PC gaming cards. less
