(GW) transient GW150914. This was followed by a second GW event observed on
December 26, 2015. Both events were inferred to have arisen from the merger of black holes
in binary systems. Such a system may emit neutrinos if there are magnetic fields and disk
debris remaining from the formation of the two black holes. With the surface detector array of
the Pierre Auger Observatory we can search for neutrinos with energy E ν above 100 PeV …
