Abstract
Abstract The VLITE-Fast experiment combines the wide-field-of-view of single dish antennas operating at low frequency with the high angular resolution furnished by the 3–30 km baselines of the VLA, making it ideal for the detection and precise localization of radio transients. We describe the VLITE-Fast experiment, its capabilities, and operational status, and we briefly overview its main science case, the detection of fast radio bursts (FRBs) and determination of their host galaxies. We report on commissioning observations in an incoherent mode prohibiting precise localization. These include discovery of FRB 20200405A, detected during early science operations at dispersion measure (DM) = 212.3 pc cm−3, strongly in excess of the Galactic DM along the line of sight.
