Abstract Nuclear clusters (NCs) in late-type spiral galaxies have more in common withmassive, dense globular clusters (GCs) or super star clusters (SSCs) thanearly-type galactic bulges. They may host stellar- or intermediate-mass blackholes (IMBHs), and if so may also be X-ray bright. We propose an XMM-Newtonsurvey of nearby galaxies with well-studied NCs in order to determine how manyof these NCs have appreciable X-ray emission. These observations will serve as apilot study for a broader program targeting galactic NCs, which will allow us toplace important constraints on the parameter space for models of IMBH formation,and to compare the X-ray properties and remnant population of these threeclasses of star clusters (NCs, GCs, SSCs) as a function of environment, age, star-formation hist.

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.
