Parkes observations for project P892 semester 2019APRS_05
SUPERBx looks at the highest Galactic latitudes in a search for pulsars and fast radio bursts (FRBs). We use optimised GPU codes and supercomputing to search for these, 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 telesc... moreopes. Our pulsar discoveries are typically nearby scintillating sources, intermittent sources and those in interesting binary systems. Our FRB discoveries have discovery lags of ~1 second, rather than months/years and these feed rapid alerts to the world-wide follow-up community via a dedicated VOEvent format an Astronomer's Telegrams. The goal of this is to allow localisation of the discovered FRBs. 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
