Neutrino08 Day 6c

ANITA is a radio balloon experiment, which is flown around Antarctica to view a vast expanse of ice and then (ideally) landed neatly. Despite problems with the last flight, 18 days of good live time were recovered for an average 1.2 km depth of ice. For the next flight they expect a factor of 5 improvement in the $\nu$ rate. Some candidate geosynchrotron events were observed, but satellite data still needs to be checked carefully (solid state relays on satellites can cause false events).

B. Dingus overviewed multiwavelength astronomy and, taking advantage of the late lecture slot, showed a few photos of her trip to Franz Josef glacier (and Arthur's Pass). Potential neutrino sources were introduced with this stunning image of the Crab nebula, along with other examples. Unidentified high latitude EGRET sources were also mentioned. And GLAST is due to launch on Thursday! One day of GLAST operation should match 9 years of EGRET. Dingus actually works for Milagro, a TeV gamma ray observatory in Mexico that was turned off in April 2008. HAWC was discussed as a promising future detector.

Beautiful photo of the Crab! Multiwavelength astronomy has led to many pretty pictures. The Alpha Magnetic Spectrometer would find many cosmic rays from its perch on the Space Station. Currently AMS is included in a bill winding its way through the US Congress.
