Description Surveys resolve substantial fractions of the hard cosmic X-ray background into individual sources, but the accounting is incomplete. We have indirectly detected an AGN in an edge-on, optically "normal" galaxy via the observation of water megamaser emission, which elsewhere exists exclusively in type-2 AGN. We propose a 33 ksec EPIC observation to confirm spectroscopically the presence of an AGN in IRASF01063-8034. Detection would support arguments that nearby galaxies could contain previously unrecognized AGN, with bearing on the origin of the hard X-ray background. Detection would also suggest radio surveys of edge- on systems, looking for masers, would usefully supplement X-ray surveys.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
