Talks on transients observed by radio telescopes
The radio sky is highly dynamic, hosting transient and variable sources on timescales from milliseconds to years. In this talk, I will present an overview of the work of the Sydney Radio Transients Group, focusing on the discovery and characterisation of radio transients across a wide range of timescales. Our science spans fast radio bursts, radio afterglows of gravitational-wave events, and...
Fast radio bursts (FRBs) are energetic pulses of radio emission typically lasting a few milliseconds, which encode in their telltale parabolic sweeps in time and frequency a fossil record of their passage through ionised gas between and within galaxies. The Commensal Real-time ASKAP Fast Transients (CRAFT) survey was the first to localise a non-repeating FRB to sub-arcsecond precision, and has...
The last decade of investigations into the extragalactic radio sky has led to a paradigm shift, with all-together new and uncharacterized populations of radio transients emerging for the first time. Upgrades in multiple fast radio burst (FRB) experiments have led to the first samples of precisely localized events, enabling host galaxy associations and detailed observations of the immediate...
The Canadian Hydrogen Observatory and Radio Transient Detector (CHORD), currently under construction, is the successor to the highly successful CHIME array, and is a flagship project of Canadian radio astronomy. Though not an original design goal, CHIME was found to be an immensely capable detector of Fast Radio Bursts, and CHORD may have unforeseen capabilities in the same spirit, as a...
