Title Weighing the Dark Matter Halo of the Fastest-Spinning Super Spiral


DOI https://doi.org/esa-[xxxxxxx]
Author Dr Patrick Ogle
Description Super spirals are the most massive spiral galaxies in the universe. They have very high rotation speeds and specific angular momenta that break from the Tully-Fisher and Fall scaling relations. We suspect that they are under-massive for their dark matter halos, with their baryonic mass limited by inefficient gas cooling and accretion. Alternatively, they may have been spun up by cold accretion flows or gas-rich major mergers. In order to definitively distinguish between these two possible super spiral formation scenarios, we propose to measure the luminosity and temperature of the hot gas halo of the fastest spinning super spiral 2MFGC 12344 using XMM-Newton.

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.
