Description Recent observations of X-ray faint early-type galaxies have yielded surprising results. Firstly, there seems to be substantially lower ISM metal enrichment than expected from observations of the brightest galaxies and groups, and secondly the existence of dark matter halos in them, which are predicted by N-body cosmological simulations, has been called into question. Both of these results suggest a sharp change in galaxy properties at intermediate luminosities. However, data-points from galaxies between these extremes are rare. We propose a 60ks observation of the S0 NGC1332, to supplement Chandra data that are providing tantalizing but inconclusive constraints in both of these key areas.

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.
