Constraints on Gamma‐Ray Emission from the Galactic Plane at 300 TeV
Constraints on Gamma‐Ray Emission from the Galactic Plane at 300 TeV
We describe a new search for diffuse ultra-high-energy gamma-ray emission associated with molecular clouds in the Galactic disk. The Chicago Air Shower Array (CASA), operating in coincidence with the Michigan muon array (MIA), has recorded over 2.2 × 109 air showers from 1990 April 4 to 1995 October 7. We …
