Abstract

We present here, follow-up observations of four Binary black hole BBH events
performed with the High Energy Stereoscopic System (H.E.S.S.) in the Very High
Energy (VHE) gamma-ray domain during the second and third LIGO/Virgo
observation runs. Detailed analyses of the obtained data did not show
significant VHE emission. We derive integral upper limit maps considering a
generic $E^{-2}$ source spectrum in the most sensitive H.E.S.S energy interval
ranging from 1 to 10 TeV. We also consider Extragalactic Background Light
absorption effects and derive integral upper limits over the full accessible
energy range. We finally derive upper limits of the VHE luminosity for each
event and compare them with the expected VHE emission from GRBs. These
comparisons allow us to assess the H.E.S.S. gravitational wave follow-up
strategies. For the fourth GW observing run O4, we do not expect to
fundamentally alter our observing strategy, and will continue to prioritize sky
coverage like for the previous runs
