Query: Studying Cosmic-ray Interactions in Giant Molecular Clouds with the HAWC
  Gamma-ray Observatory   The cosmic-ray flux in the Galaxy can be characterized by combining the
knowledge of the distribution of gas in the Galaxy and the observation of gamma
rays. We analyze the data from the HAWC Observatory to look for gamma rays in
three galactic giant molecular clouds, that are outside the galactic plane
($|b|>5^{\circ}$). We can then test the paradigm that the measured local
cosmic-ray flux is the same as the "sea" of Galactic cosmic rays. Due to its
large field of view, and high duty cycle, HAWC is suitable to search for gamma
rays from large structures in the TeV gamma-ray regime. We present here
preliminary results from measurements of the Aquila Rift, Hercules and Taurus
molecular clouds.
