"The time when Ginzburg and Syrovatsky met HESS and what they told".
The VHE gamma ray observations of H.E.S.S. permit direct tests of the hypothesis of Ginzburg and Syrovatskii, that galactic cosmic rays are accelerated in supernova remnants. We discuss how it is possible to use these VHE gamma ray data to deduce the flux of cosmic rays with the minimum theoretical bias (the inverse...

An interesting possible detection mechanism for observing ultra high energy neutrinos is that of acoustic detection. The speaker will introduce this technique and review the current status of research activities in this field across Europe, the US and Russia.

We report new results on experiments searching for cosmic neutrino fluxes, including the Antarctic Impulsive Transient Antenna (ANITA) experiment, which completed a 36-day flight of a long-duration balloon payload, in Dec. 2006 - Jan. 2007. We search for impulsive events that could be associated with ultra-high energy neutrino interactions in the ice, and derive limits that constrain several...
