Fast radio bursts (FRBs) are typically milli-second-duration luminous radio transients whose source remain debatable. Caltech/ OVRO's Deep Synoptic Array-110 (DSA-110) is the only radio interferometer designed specifically for FRB searching and localization. By mid-2023, DSA-110 has doubled the number of localized FRBs. First, I will highlight the high-resolution burst morphology of a sample of localized DSA FRBs and their connection with host galaxies. Second, I will introduce a study of FRB 121102, one of the only two active repeating FRBs associated with a persistent radio source (PRS), using the VLA and Keck data, and discuss whether or not the persistent radio emission could come from an AGN. Finally, I will briefly review a technique that constrains the energy ratio emitted by FRBs and their potential multiwavelengh counterparts using blind multiwavelengh survey databases.
