| Abstract | Super spirals are the most massive spiral galaxies in the universe. They havevery high rotation speeds and specific angular momenta that break from theTully-Fisher and Fall scaling relations. We suspect that they are under-massivefor their dark matter halos, with their baryonic mass limited by inefficient gascooling and accretion. Alternatively, they may have been spun up by coldaccretion flows or gas-rich major mergers. In order to definitively distinguishbetween these two possible super spiral formation scenarios, we propose tomeasure the luminosity and temperature of the hot gas halo of the fastestspinning super spiral 2MFGC 12344 using XMM-Newton. |

| 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. |
