FRB20250613A: a remarkable repeating FRB with apparent millisecond-timescale scattering variations

T. Dial, A. T. Deller, Alexa C. Gordon +8

FRB20250613A is a repeating FRB discovered by the Australian SKA Pathfinder and localised to a low-metallicity dwarf galaxy at a redshift of . FRB 20250613A…

High-time-resolution properties of 35 fast radio bursts detected by the Commensal Real-time ASKAP Fast Transients Survey

D. R. Scott, T. Dial, A. Bera +11

We present microsecond-resolution, coherently-dedispersed, polarimetric measurements of 35 fast radio bursts (FRBs) detected during the Commensal Real-time ASKAP Fast Transients (C…

Mapping the Spatial Distribution of Fast Radio Bursts within their Host Galaxies

Alexa C. Gordon, Wen-fai Fong, Adam T. Deller +23

We present deep optical and near-infrared observations of the host galaxies of 34 fast radio bursts (FRBs) detected by the Commensal Real-time ASKAP Fast Transient (CRAFT) survey o…

A nanosecond-duration radio pulse originating from the defunct Relay 2 satellite

C. W. James, A. T. Deller, T. Dial +14

We report the detection of a burst of emission over a 695.5 MHz-1031.5 MHz bandwidth by the Australian Square Kilometre Array Pathfinder, ASKAP. The burst was localised through ana…

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…

Unusual intra-burst variations of polarization states in FRB 20210912A and FRB 20230708A : Effects of plasma birefringence?

Apurba Bera, Clancy W. James, Mark M. McKinnon +6

Fast radio bursts (FRBs) are highly energetic events of short-duration intense radio emission, the origin of which remains elusive till date. Polarization of the FRB signals carry…
