Abstract We propose XMM-Newton observations of three barred galaxies selected for theirstrong radio emission and remarkable magnetic field structures. EPIC spatial andspectral information will be used in combination with our radio data to studythe influence of bar lengths and compression strengths on the enhancement ofcircumnuclear star formation and nuclear activity. We will study the effects ofmagnetic fields on the evolution of diffuse X-ray halos generated by hot gasoutflowing from starforming regions. We will investigate if the distribution ofpoint-like sources, especially ULXs, is correlated with starforming regions atthe ends of the bars. EPIC data will be complemented with Chandra observationsto disentangle nuclear and circumnuclear emission.

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.
