We propose a multiwavelength observation of the most radio-loud Narrow-LineSeyfert 1 galaxy (NLS1) PKS 2004--447. PKSvirgul2004--447 may be the most fascinatingobject in this rare class of NLS1 due to its extreme radio loudness compared toother members of the class, and its classification as a compact steep-spectrum(CSS) source. Both the CSS and NLS1 classification suggest that PKSvirgul2004--447 isa young AGN, however, its combination of optical and radio properties is incontradiction to what is normally observed and expected. We propose to observePKS 2004--447 at radio, optical, UV, and X-rays wavelengths simultaneously, inorder to understand the spectral energy distribution and the primary energysource at work.

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.
