Rapid Response Triggering for Radio Transients with the SKA Observatory
G. E. Anderson, S. I. Chastain, A. P. Curtin +10
Rapid-response triggering is when a telescope is able to automatically respond to an external or internal astronomical transient alert, causing it to rapidly repoint at that positi…

A fast radio burst cyclone in technicolour: evidence of plasma lensing
Pavan A. Uttarkar, Ryan M. Shannon, Kelly Gourdji +9
Fast radio bursts (FRBs) are bright, energetic, radio pulses of extragalactic origin. A dichotomy has emerged in the population: some produce repeat bursts, while the majority do n…
Mapping the Spatial Distribution of Fast Radio Bursts within their Host Galaxies

We present microsecond-resolution, coherently-dedispersed, polarimetric measurements of 35 fast radio bursts (FRBs) detected during the Commensal Real-time ASKAP Fast Transients (C…
A depolarisation census of ASKAP fast radio bursts
Pavan A. Uttarkar, Ryan M. Shannon, Kelly Gourdji +9
Fast radio bursts (FRBs) are luminous, dispersed pulses of extra-galactic origin. The physics of the emission mechanism, the progenitor environment, and their origin are unclear. S…

T. Dial, A. T. Deller, P. A. Uttarkar +8
There has been a rapid increase in the known fast radio burst (FRB) population, yet the progenitor(s) of these events have remained an enigma. A small number of FRBs have displayed…
Rocking the BOAT: the ups and downs of the long-term radio light curve for GRB 221009A

We present radio observations of the long-duration gamma-ray burst (GRB) 221009A which has become known to the community as the Brightest Of All Time or the BOAT. Our observations…
The impact of the FREDDA dedispersion algorithm on estimations with FRBs
Jordan Hoffmann, Clancy W. James, Hao Qiu +12
Fast radio bursts (FRBs) are transient radio signals of extragalactic origins that are subjected to propagation effects such as dispersion and scattering. It follows then that thes…
The Curious Case of Twin Fast Radio Bursts: Evidence for Neutron Star Origin?
Apurba Bera, Clancy W. James, Adam T. Deller +9
