Map of the Galactic center built with 1–200 GeV γ-ray photons collected by the LAT instrument during the first year of the Fermi mission (Aug. 2008/Aug. 2009). North is to the top, East to the left, and the Galactic plane runs from upper left to bottom right. Each pixel has a size of 0.1° and the image was smoothed with a Gaussian kernel of 0.15° radius. The color bar is expressed in counts and the positions of the point sources were taken from Abdo et al. (2010).
