This collection contains observational data of the fast radio bursts FRB 171209, FRB 180309, FRB 180311 and FRB 180714, detected during Parkes Pulsar Timing Array (P456) observations using the 21cm Mu... morelti-beam receiver on the Parkes 64m radio telescope.less
ARC Future Fellowship - George Hobbs - Fast Radio Bursts - Published 01 Jul 2019
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... more mystery. Some have proposed FRBs come from Crab-like pulsar giant pulses or periods of high activity of distant magnetars. Both mechanisms would generate 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
Australia Telescope National Facility - P871 - A follow-up campaign for fast radio bursts - Published 05 Oct 2018
SUPERBx is an extension to the SUPERB survey which looks at the highest Galactic latitudes in a search for fast radio bursts (FRBs). Recent results show that there is a strong latitude dependence to F... moreRB detectability so SUPERBx will search above 25 degrees in Galactic latitude. It will use 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 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 other radio telescopes (Molonglo, GMRT, MWA) 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.less
Australia Telescope National Facility - P892 - SUPERBx - The SUrvey for Pulsars & Extragalactic Radio Bursts Extension - Published 14 May 2018
SUPERBx is an extension to the SUPERB survey which looks at the highest Galactic latitudes in a search for fast radio bursts (FRBs). We will focus our efforts at high Galactic latitudes where our prev... moreious work has shown FRB detectability to be as much as 3 times higher than in the plane. 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 five 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) 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

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. Handlin... moreg 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 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

Recently there has been great success at Parkes discovering millisecond pulsars (MSPs), a class that includes some of the most interesting and scientifically valuable pulsars known. In the last few ye... morears we have discovered more than 40 MSPs though the High Time Resolution Universe Survey (P630) and Fermi searches (P675/P814). Here we propose to carry out precision timing of these sources to fully exploit these discoveries. Additionally, continue to study the most significant of the discoveries from the Parkes Multibeam Pulsar Survey (P268). To maximise scientific impact we have combined the most important sources from various previous proposals into this project, reducing total observation time required and easing the burden on the scheduler.less
