Abstract
The idea of having this workshop in Madison was born at a table on the Terrace of the Union one evening in summer 2005. Francis Halzen, Albrecht Karle and I had just attended the first TeV meeting at Fermilab. We wished to convene the community of particle physicists and "new astronomers" who were using particles to study the universe, in order to hear about their activities and the methods they were using. All of us wanted this to be a meeting between both younger and more experienced people, and both experimentalists and theorists with a common background: dealing with signals produced in the universe that are not controlled by humans.
We decided to ask the organizers of the Fermilab workshop to have a second edition in Madison. The next edition is planned for summer 2007 in the Venice region of Italy. To make the meeting more productive, we planned to have a relevant number of working group sessions and open discussions chaired by invited conveners.
We singled out seven main areas for discussion at the Workshop with self-explaining names, calling the afternoon sessions Working Groups in those areas: 1) Gamma Astronomy, 2) Ultra-High-Energy Cosmic Rays, 3) Dark Matter, 4) Neutrino Astronomy, 5) New Technologies, 6) TeV Particle (i.e., connections between cosmic-ray, high-energy and accelerator physics) and 7) Gravitational Waves. The conveners had to not only organize the schedules, but also had the unfortunate task of summarizing all of the discussions which took place in their sessions for a presentation on the last day of the conference. Our web site ( http://www.icecube.wisc.edu/tev), developed by Rene Shei, allowed anybody to submit a proposal for a talk to the conveners of the appropriate Working Group(s). We felt that allowing this possibility provided an excellent chance for unknown young students to offer interesting proposals that could then be selected.
These Proceedings collect the work of a large number of experts and extremely active representative people from the various fields of Astroparticle Physics.
