Ultra-High Energy Neutrino Follow-Up Searches of GW Events with the Pierre Auger Observatory---status and results — •Michael Schimp for the Pierre Auger collaboration — Bergische Universität Wuppertal, Gaußstr. 20, 42119 Wuppertal

The surface detector array of the Pierre Auger Observatory is sensitive to neutrinos at energies above 0.1 EeV (ultra-high energy neutrinos). Its large acceptance at this energy range makes it a complement to current neutrino telescopes, which have their peak sensitivities at lower energies. Ultra-high energy neutrinos are promising messengers to address open questions concerning the nature of ultra-high energy cosmic rays as they could be produced both at their sources and during their propagation. With the first observation of gravitational waves (GW) from a binary black hole merger (BH-BH merger) by the LIGO Collaboration in 2015, a new branch of astronomy, with the potential to contribute to resolving those open questions, has joined in. In August 2017, the LIGO/Virgo Collaborations observed for the first time a binary neutron star merger (NS-NS merger) and sent an immediate alert to pre-established partners, among which is the Pierre Auger Collaboration. We present the status and results of the ultra-high energy neutrino follow-up searches of LIGO/Virgo GW events that were performed with the Pierre Auger Observatory. These events include BH-BH merger events and the above-mentioned---so far unique---NS-NS merger event.
