W. R. Arcus, C. W. James, R. D. Ekers +11
We examine the energy distribution of the fast radio burst (FRB) population using a well-defined sample of 63 FRBs from the ASKAP radio telescope, 28 of which are localised to a ho…
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…
