| Description | Recent efforts to model the formation of disk galaxies have focused on the dissipative collapse of the disk inside a dark matter halo, and suggest that high and low surface brightness disks (HSBs and LSBs) form from low and high angular momentum halos, respectively. If correct, the largest LSBs reside in halos with mass comparable to those of poor groups of galaxies, while HSBs reside in much less massive halos. We propose to observe three giant disk galaxies, two LSBs and one HSB, with the EPIC pn camera on XMM with the following goals: (1) to measure the hot gas to stellar mass ratio,(2) to probe the dark halo structure and density profile in low and high angular momentum systems, and (3) to identify the baryon fraction and efficiency of disk collapse |

| 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. |
