Abstract
PKS 2155-304 is a well known GeV-TeV source and one of the brightest blazars in the Fermi sky. More than two years of Fermi operations provides the most extensive light curve of this object between 200 MeV and 300 GeV. Together with monitoring from RXTE, these data allow the study of the temporal and spectral behavior of PKS 2155-304 in the two energy bands. A time dependent SSC model is used to fit the time-averaged SED (i) to reproduce the temporal behavior of a particular period, and (ii) to interpret the statistical properties of the light curves. Our analysis provides a complete picture of the emission mechanisms on long time scales for PKS 2155-304.
