| Abstract | Ring galaxies are unique laboratories to study the effects of galaxyinteractions: they are characterized by high SFR,enhanced X-ray emission, andlarge number of ULXs. However only 4 source are published. We selected allcollisional rings at z<0.02 from the Arp&Madore sample of southern ring galaxiesfor a statistical sample of 12. As a first step we ask for XMM-Newton snapshotsof 8 galaxies that suit the XMM-Newton characteristics. We expect to detect thering as a bright X-ray source, to which both gas and point sources (mostly ULXs)contribute. The non-detection of X-ray sources would represent an unexpected andimportant discovery, indicating that known the sources are quite different fromthe rest of the population. |

| 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. |
