Parkes observations for project P858 semester 2014OCTS25
SUPERB is a large-scale survey for pulsars and extragalactic radio bursts. It will 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... more pulsars discovered will enable studies of the interstellar medium, allow us to more accurately constrain the MSP luminosity function (which informs estimates of the SKA yield of MSPs), tests of theories of gravity and several will contribute to the precision timing projects of the PPTA. The FRBs discovered will have much more associated information than all previous detections. Firstly the discovery lag will be ~1 second, rather than months/years. The Parkes observations will be shadowed by the Molonglo telescope to allow, for the first time, localisation of 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. The survey will discover ~20 MSPs, ~100 slower pulsars and ~10 FRBs. less

P858 - SUPERB - A SUrvey for Pulsars & Extragalactic Radio Bursts
We will survey the sky to find pulsars and fast radio bursts (FRBs). Pulsars, the remnants of supernova explosions that occur at the end of massive stars' lives, are reborn city-sized 'zombie stars' which rotate faster than a kitchen blender. They emit a beacon of radio light, detectable on Earth as a pulse once every time it rotates. The rotation ... moreof the star is so stable that we can use the radio pulses as the ticks of a cosmic clock. This means we can use them as tools for investigating physics, e.g. testing Einstein's General Theory of Relativity by examining the clocks' behaviour in warped space-times Pulsars are quite 'nearby' at only a few thousand lightyears, but FRBs are about a million times more distant. 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 you get when an unstable pulsar collapses to a black hole. We will identify FRBs with Parkes and the Molonglo telescope (300 km from Parkes) in tandem. Using both 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
