Modeling of the multiwavelength emission of M87 with H.E.S.S. observations

Abstract

M87 is the first extragalactic source detected in the TeV range that is not a blazar. The large scale jet of M87 is not aligned with the line of sight. Modification of standard emission models of TeV blazars appears necessary to account for the gamma-ray observations made by H.E.S.S. despite this misalignment. We present a new multi-blob synchrotron self-Compton model that deals explicitly with large viewing angles and moderate values of the Lorentz factor inferred from MHD simulations of jet formation.Comment: 4 pages, 4 figures; to appear in "SF2A 2007 proceedings", eds.
