  • Pulsars and Fast Transients

Project Details

Fast radio bursts are the brightest radio explosions in astronomy. Lasting typically a thousandth of a second, we view them from galaxies so distant that their light was emitted when the Universe was half its current age. Our collaboration, CRAFT, is using the Australian Square Kilometre Array Pathfinder to detect fast radio bursts, identify their host galaxies, and reconstruct their time profiles down to 3 nanoseconds resolution. The aim is to determine what physical mechanism is responsible for their extreme brightness. In this project, the student will analyse FRB time profiles, and use the statistical properties of the radio intensity (via a quantity known as the “modified coherence function”) to search for hints of the emission mechanism.

Timing profiles of 10 ASKAP FRBs

The time-frequency profiles of 10 fast radio bursts (FRBs) detected by the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope. These show a diversity of structure in both the time- and frequency-domains. What can this tell us about the emission mechanism? This project aims to find out.
