Multimessenger Prospects with Gravitational Waves and Neutrinos after LIGO's First Discovery

The recent observation of gravitational waves unveiled numerous opportunities in astrophysics, as well as in the study the cosmos and the laws of physics. With annually improving detectors, gravitational wave observations are set to rapidly expand in the next years. We briefly introduce the first gravitational-wave detection and its background. We will then outline the status, plans and opportunities in multimessenger observations, in particular with neutrinos, which will broaden our horizon with gravitational waves. (paper)
