Black Holes, Shredded Stars and Cosmic Neutrinos — •Robert Stein — DESY Zeuthen, Platanenallee 6, 15738 Zeuthen, Germany — California Institute of Technology, 1216 E California Blvd, 91125 Pasadena, USA

If a star is unlucky enough to pass close to a supermassive black hole, the black hole's extreme gravitational pull will cause the star to disintegrate. The resulting stellar debris will ultimately fall into the black hole, but not before releasing a spectacular flare across the entire electromagnetic spectrum, in a so-called `Tidal Disruption Event' (TDE). These TDEs represent some of the most extreme astrophysical processes in the universe, and act as one of nature's `cosmic accelerators'. I will discuss the study of TDEs, and how cosmic neutrinos can be used to probe the underlying particle acceleration in these objects.
