Limits on precursor and afterglow radio emission from a fast radio burst in a star-forming galaxy
Shivani Bhandari, Keith W. Bannister, Emil Lenc +17
We present a new fast radio burst (FRB) at 920 MHz discovered during commensal observations conducted with the Australian Square Kilometre Array Pathfinder (ASKAP) as part of the C…
Spectropolarimetric analysis of FRB 181112 at microsecond resolution: Implications for Fast Radio Burst emission mechanism
Hyerin Cho, Jean-Pierre Macquart, Ryan M. Shannon +14
We have developed a new coherent dedispersion mode to study the emission of Fast Radio Bursts that trigger the voltage capture capability of the Australian SKA Pathfinder (ASKAP) i…
First Constraints on Compact Dark Matter from Fast Radio Burst Microstructure
Mawson W. Sammons, Jean-Pierre Macquart, Ron D. Ekers +5
Despite existing constraints, it remains possible that up to of all dark matter is comprised of compact objects, such as the black holes in the 10-100\,M range whose…
The low density and magnetization of a massive galaxy halo exposed by a fast radio burst
J. Xavier Prochaska, Jean-Pierre Macquart, Matthew McQuinn +16
Present-day galaxies are surrounded by cool and enriched halo gas extending to hundreds of kiloparsecs. This halo gas is thought to be the dominant reservoir of material available…
