We report on a search for persistent radio emission from the one-off FastRadio Burst (FRB) 20190714A, as well as from two repeating FRBs, 20190711A and20171019A, using the MeerKAT radio telescope. For FRB 20171019A we alsoconducted simultaneous observations with the High Energy Stereoscopic System(H.E.S.S.) in very high energy gamma rays and searched for signals in theultraviolet, optical, and X-ray bands. For this FRB, we obtain a UV flux upperlimit of 1.39x10^-16 erg/cm^-2/s/Amstrong, X-ray limit of ~ 6.6x10^-14erg/cm^-2/s and a limit on the very-high-energy gamma-ray flux (Phi) (E > 120GeV) < 1.7 x 10^-12 erg/cm^-2/s. We obtain a radio upper limit of ~15microJy/beam for persistent emission at the locations of both FRBs 20190711Aand 20171019A, but detect diffuse radio emission with a peak brightness of ~53microJy/beam associated with FRB 20190714A at z = 0.2365. This represents thefirst detection of the radio continuum emission potentially associated with thehost (galaxy) of FRB 20190714A, and is only the third known FRB to have such anassociation. Given the possible association of a faint persistent source, FRB20190714A may potentially be a repeating FRB whose age lies between that of FRB20121102A and FRB 20180916A. A parallel search for repeat bursts from theseFRBs revealed no new detections down to a fluence of 0.08 Jy ms for a 1 msduration burst.
