Matthew Bailes (Swinburne): Discovery of a Population of Fast Radio Bursts

Seminar: RAL Seminars | June 21 | 10:30-11:30 a.m. | B1 Hearst Field Annex | Note change in time

The Parkes High Time Resolution Survey for pulsars and fast transients has been surveying the southern sky in three bands based on galactic latitude.

The survey commenced with a quick pass over |b| less than 15 deg and discovered 25 millisecond pulsars including the celebrated "Diamond Planet".

The second part of the survey is observing |b| less than 3.5 deg for 70 minutes per pointing and the third looking at all sky less than declination 0 degrees. Processing of the off-plane region started in earnest in 2011 and has already discovered a large number of "Lorimer bursts" our to cosmologically interesting dispersion measures and far in excess of the original burst.

The bursts will be discussed in detail as well as plans to refurbish the old 18,000 sq meter Mills Cross "Molonglo" radio telescope into a dedicated burst finder and the engineering behind a novel software correlator for it.
