51. Search for UHE neutrinos – in coincidence with LIGO GW150914 event – with the Pierre Auger ObservatoryLili Yang, 2016, published scientific conference contribution abstract Abstract: The first gravitational wave transient GW150914 was observed by Advanced LIGO on September 14th, 2015 at 09:50:45 Universal Time. In addition to follow-up electromagnetic observations, the detection of neutrinos will probe deeply and more on the nature of astrophysical sources, especially in the ultra-high energy regime. Neutrinos in the EeV energy range were searched in data collected at the surface detector of the Pierre Auger Observatory within ± 500 s and 1 day after the GW150914 event. No neutrino candidates were found. Based on this non-observation, we derive the first and only one neutrino fluence upper limit at EeV energies for this event at 90% CL, and report constraints on existence of accretion disk around mergers.

53. Education, Outreach and Public Relations of the Pierre Auger ObservatoryCharles Timmermans, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Darko Veberič, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, 2015, published scientific conference contribution Abstract: The scale and scope of the physics studied at the Pierre Auger
Observatory continue to offer significant opportunities for
original outreach work. Education, outreach and public
relations of the Auger Collaboration are coordinated in a
dedicated task whose goals are to encourage and support
a wide range of efforts that link schools and the public with
the Auger scientists and the science of cosmic rays, particle
physics, and associated technologies. We focus on the impact of
the Collaboration in Mendoza Province, Argentina and beyond.
The Auger Visitor Center in Malargüe has hosted over 95,000
visitors since 2001, and a fifth Collaboration-sponsored
science fair was held on the Observatory campus in November
2014. The Rural Schools Program, which is run by Observatory
staff and which brings cosmic-ray science and infrastructure
improvements to remote schools, continues to broaden its
reach. Numerous online resources, video documentaries, and
animations of extensive air showers have been created for wide
public release. Increasingly, collaborators draw on these
resources to develop Auger related displays and outreach events
at their institutions and in public settings to disseminate the
science and successes of the Observatory worldwide. We also
highlight education and outreach activities associated with the
planned upgrade of the Observatory’s detector systems and
future physics goals.
