Description Ring galaxies are unique laboratories to study the effects of galaxy interactions: they are characterized by high SFR,enhanced X-ray emission, and large number of ULXs. However only 4 source are published. We selected all collisional rings at z<0.02 from the Arp&Madore sample of southern ring galaxies for a statistical sample of 12. As a first step we ask for XMM-Newton snapshots of 8 galaxies that suit the XMM-Newton characteristics. We expect to detect the ring 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 and important discovery, indicating that known the sources are quite different from the rest of the population.

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.
