Here we propose to observe the extremely massive, rapidly rotating, relativisticjet launching, spiral galaxy 2MASX J23453268-0449256 for 85ks to observe its hothalo, measure its mass content and map its morphology. It is extremely rare fora massive spiral galaxy to eject relativistic jets, as they are nearly alwayslaunched from the nuclei of bulge dominated ellipticals and not flat spirals. Itis clear that J2345-0449 is an extremely rare system whose properties challengethe standard paradigm for the formation of relativistic jets in AGN. DetailedX-ray observations are necessary to understand this system and complement theexcellent HST, Gemini, GMRT and VLA data.

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.
