We request a 35ksec XMM observation of the gamma-ray emitting compact symmetricradio source PMNJ1603-4904 as a crucial part of the first simultaneous radio togamma-ray campaign on this object. Constraining the X-ray spectrum of thecompact radio source is needed to properly model the broadband SED, which isessential for understanding the physical nature of this unusual object. TheSwift detection allows no spectral modeling of its very faint X-ray counterpart,hence, precise spectral investigations with XMM are strongly required.PMNJ1603-4904 is one of the few young radio galaxy candidates associated with abright gamma-ray source, thus it plays a key role in investigating theunderlying emission mechanism of newly born active galaxies.

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.
