Radiation pressure powers quasar broad absorption line winds but fails to drive galaxy feedback

We present a deep learning approach to classify fast radio bursts (FRBs) based purely on morphology as encoded on recorded dynamic spectrum from CHIME/FRB Catalog 2. We implemented…
A fast radio burst from the first 3 billion years of the Universe

Fast radio bursts (FRBs) are enigmatic millisecond-duration signals which encode otherwise unattainable information on the plasma which permeates our Universe, providing insights i…
A DM relation for FRB hosts?
Lluis Mas-Ribas, Clancy W. James
It has been proposed that measurements of scattering times () from fast radio bursts (FRB) may be used to infer the FRB host dispersion measure (DM) and its redshift. This appro…
