| Abstract: |
Fast radio transients are rich with physical information about the coherent emission mechanisms that generate them and the media they propagate through. We describe the science potential of fast transients at the ngVLA with a focus on the new class of extragalactic transient known as Fast Radio Bursts (FRBs). The rarity of the bursts makes them challenging targets for dedicated observing, but their short duration and high brightness opens the possibility of detection via real-time, commensal searches. We advocate for a correlator architecture that provides access to high-time resolution data products and allows for the potential addition of dedicated computing for real-time analysis. The novel frequency coverage of the ngVLA will test origin models and potentially find FRBs in novel environments. |
