Deep Synoptic Array Science: First FRB and Host Galaxy Catalog

Understand

Fast Radio Bursts (FRBs) are a powerful and mysterious new class of transient that are luminous enough to be detected at cosmological distances.

• By associating FRBs to host galaxies, we can measure intrinsic and environmental properties that test FRB origin models, in addition to using them as precise probes of distant cosmic gas.
• The Deep Synoptic Array (DSA-110) is a radio interferometer built to maximize the rate at which it can simultaneously detect and localize FRBs.
• Here, we present the first sample of FRBs and host galaxies discovered by the DSA-110.
