Title:LSI +61 303 from the Fermi LAT Perspective
Abstract:The Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope has been observing the sky in gamma rays since August 2008. It scans the entire sky above 20 MeV every 3 hours with unprecedented sensitivity in the high energy range, making it an ideal monitor for binary systems. Two years of observations at GeV energies bring new insights into LSI +61 303's behavior, notably variability in its base flux levels and orbital modulation. In this talk, we will present LAT results on LSI +61 303 from two years of observation and present a multi wavelength picture of the source, discussing their implications for understanding of the nature of the system.
