New TeV Gamma Sources and a Surprising Cosmic Ray Anisotropy - Recent Results from Milagro
Milagro was a water-Cherenkov air shower array that operated in the Jemez Mountains above Los Alamos, NM from 2000 until 2008. Milagro was sensitive to air showers from 100 GeV through 100 TeV and developed a method for effectively rejecting hadron induced showers to provide a first wide-field look at the TeV gamma-ray sky. With the recent release of the Fermi (GLAST) bright source list, we have the opportunity to compare what is seen in the TeV with the bright sources by Fermi in the GeV. In this talk we will show the results of this comparison including first evidence for a number of newly discovered TeV gamma-ray sources. We also discuss the recent surprising Milagro discovery of two regions of localized excess of cosmic rays on the 10 degree scale visible in the Northern Sky.
