Description

Recent work has confirmed the presence of a gamma-ray excess in data from the Fermi Space Telescope extending at least 10 degrees from the Galactic Center. I will describe recent progress in characterizing this signal by using photons with the highest quality angular reconstruction, with an emphasis on the extended "inner galaxy" region. I will focus on cross-checks we have performed to distinguish this signal from a mismodelled background, and the spatial properties of the signal including its high degree of sphericity.
