Abstract

Fast Radio Bursts (FRBs) are powerful bursts of radio emission lasting mere milliseconds, that almost never repeat, and come from somewhere outside our Galaxy. Until quite recently however we could not definitively associate any FRB that did not repeat with a host galaxy. The Australian Square Kilometre Array Pathfinder (ASKAP) now has a unique capability to not just detect new FRBs, but also determine their positions to better than 1 arcsecond, allowing us to then use the ESO Very Large Telescope in Chile to study their environment and potential progenitors. FRBs are potentially extremely valuable cosmological probes, revealing to us where the "missing baryons" reside within the intergalactic medium.

Biography

Dr Stuart Ryder (B.Sc. Hons, Canterbury 1988) is a Program Manager with Astronomy Australia Ltd, overseeing Australia's Strategic Partnership with the European Southern Observatory. He is also an Adjunct Fellow with the Dept of Physics & Astronomy at Macquarie University. He has used a number of optical/infrared telescopes including the AAT, Gemini, Very Large Telescope, Keck, and Subaru, as well as radio telescopes to study core-collapse supernovae, and now heads a groundbreaking study of the host galaxies of Fast Radio Bursts.
