A fast radio burst localized at detection to an edge-on galaxy using very-long-baseline interferometry
Tomas Cassanelli, Calvin Leung, Pranav Sanghavi +48
Fast radio bursts (FRBs) are millisecond-duration, luminous radio transients of extragalactic origin. These events have been used to trace the baryonic structure of the Universe us…
Constraints on the Intergalactic and Local Dispersion Measure of Fast Radio Bursts with the CHIME/FRB far side-lobe events
