Aims. Following the detection of the fast radio burst FRB150418 by the SUPERB project at the Parkes radio telescope, we aim to search for
very-high energy gamma-ray afterglow emission.
Methods. Follow-up observations in the very-high energy gamma-ray domain were obtained with the H.E.S.S. imaging atmospheric Cherenkov
telescope system within 14.5 hours of the radio burst.
Results. The obtained 1.4 hours of gamma-ray observations are presented and discussed. At the 99 % C.L. we obtained an integral upper limit on
the gamma-ray flux of Φγ(E > 350 GeV) < 1.33 × 10−8 m−2
s
−1
. Differential flux upper limits as function of the photon energy were derived and
used to constrain the intrinsic high-energy afterglow emission of FRB 150418.
Conclusions. No hints for high-energy afterglow emission of FRB 150418 were found. Taking absorption on the extragalactic background light
into account and assuming a distance of z = 0.492 based on radio and optical counterpart studies and consistent with the FRB dispersion, we
constrain the gamma-ray luminosity at 1 TeV to L < 5.1 × 1047 erg/s at 99 % C.L.
