Abstract | Compact groups of galaxies are an extreme class of objects and excellentlaboratories for the study of galaxy interactions and their effects. Recentoptical results indicate that we observe them in a wide range of properties,that could be understood in a broad evolutionary picture. X-ray data are ofparamount importance to substantiate the evolutionary picture suggested by the optical, since they provide crucial information on dynamical and activity stage.This proposal aims at observing 6 compact groups, selected from the new SouthernCompact Groups catalogue, chosen in a range of properties in terms of their supposed evolutionary stage, to strengthen the above evolutionary picture. Itcould enable us solve what until now has been dubbed the compact groups paradox. |

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. |
