Title NGC 1132: A Fully-Merged Optically Dark Group


DOI https://doi.org/10.5270/esa-ypgdk4w
Author Prof William Mathews
Description We propose to observe NGC 1132, an isolated E galaxy surrounded by an ensemble of faint dwarf galaxies. Evidently, all of the more luminous original group members merged to form NGC 1132. It has a remarkably high total mass to light ratio suggesting that star formation in the group is unusually inefficient. XMM temperature measurements will provide an accurate dark mass profile out to half the virial radius. The radial variation of the Fe abundance in the hot gas will define the total number of supernova that have occurred over time. The simplicity of this fully merged system is ideal for gas dynamical calculations, which, when compared to XMM observations, afford a unique opportunity to learn about galaxy evolution.

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.
