|Title||HOW TO SOLVE THE COMPACT GROUP PARADOX WITH XMM--NEWTON|
|Author||Dr ANGELA IOVINO|
|Description||Compact groups of galaxies are excellent laboratories for the study of galaxy interactions and their effects. Recent optical results indicate that we observe them in a wide range of properties closely linked to an evolutionary picture based on the level of activity and frequency-strength of the interactions among members. To substantiate this picture, X-ray data are needed to provide crucial information on both dynamical (by probing the system.s potential), and activity (by completing the information on galaxy activity) stages of groups. We propose to observe 4 additional groups in the Southern Compact Groups catalogue chosen to represent different evolutionary stages to continue our study of the X-ray properties of these systems in this context.|

|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.
