TITLE:  Fundamental Physics from the Sky

ABSTRACT: Can we learn about New Physics with astronomical and
astro-particle data? Understanding how this is possible is key to
unraveling one of the most pressing mysteries at the interface of
cosmology and particle physics: the fundamental nature of dark matter.
Rapid progress may be within grasp in the context of an approach which
combines information from high-energy particle physics with cosmic-ray and
traditional astronomical data. I discuss recent puzzling data on
cosmic-ray electrons and positrons and their interpretation. I show how
the Fermi Space Telescope will soon shed light on those data as well as
potentially on several dark matter particle properties. I then introduce a
novel approach to particle dark matter searches based on the
complementarity of astronomical observations across the electromagnetic
spectrum, from radio to X-ray and to gamma-ray frequencies.
