Abstract
We report performance verification observations of the giant elliptical gal axy M 87 in the Virgo Cluster with the MOS, pn, and optical monitor instrum ents on board of XMM-Newton. With the energy sensitive imaging instruments MOS and pn we obtain the first spatially constrained X-ray spectra of the n ucleus and the jet of the galaxy. The good photon statistics of the pn and MOS allow a detailed analysis of the radial temperature and abundance distr ibution of 6 elements. The data provide no indication of a multi-temperatur e structure for radii greater than or equal to2'. An apparent sharp metal a bundance drop deduced for the regions inside this radius is probably due to resonant line scattering.
