We propose XMM EPIC observations of the GHz Peaked Spectrum (GPS) source2352+495 and the Compact Steep Spectrum (CSS) source 3C303.1. The proposedobservations will allow us to finally detect the GPS and CSS radio galaxies thusprobing the AGN and host galaxy properties of this key class of radio source. We will (1) compare their AGN and host galaxy X-ray properties with those ofother radio galaxies studied by XMM; (2) constrain the ionization of theemission lines; (3) and test the evolving source model of Heinz et al (1998).A detection of the X-ray emission from the shocked gas will prove that the radiosource is expanding supersonically in the ambient medium consistent with theevolution scenario and will also probe fundamental physics of the radio source.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
