ABSTRACT We report on a search for persistent radio emission from the one-off fast burst (FRB) 20190714A, as well two repeating FRBs, 20190711A and 20171019A, using MeerKAT telescope. For FRB we also conducted simultaneous observations with High-Energy Stereoscopic System (H.E.S.S.) in very high-energy gamma rays searched signals ultraviolet, optical, X-ray bands. this FRB, obtain UV flux upper limit of $1.39 \times 10^{-16}~{\rm erg\, cm^{-2}\, s^{-1}}$Å−1, $\sim 6.6 10^{-14}~{\rm s^{-1}}$ high energy gamma-ray $\Phi (E\gt 120\, {\rm GeV}) \lt 1.7\times 10^{-12}\, \mathrm{erg\, s^{-1}}$. ∼15 $\mu$Jy beam−1 at locations both FRBs 20171019A MeerKAT. However, detected an almost unresolved (ratio integrated to peak is ∼1.7 beam) emission, where synthesized beam size was ∼ 8 arcsec brightness 53\, \mu$Jy 86\, e-MERLIN, possibly associated 20190714A z = 0.2365. This represents first detection continuum potentially (as-yet) non-repeating FRB. If association confirmed, one strongest remaining distinction between repeaters non-repeaters would no longer be applicable. A parallel repeat bursts these revealed new detections down fluence 0.08 Jy ms 1 duration burst.
