We propose to investigate the spatial and spectral properties of the hot ISM inthe nearby early-type galaxy NGC 4261. The galaxy is known to have a verypeculiar asymmetric distribution of X-ray sources and of globular clusters, anactive nuclear radio source with unique two-sided radio jet and an extended andmorphologically disturbed ISM. We will obtain a firm determination of theproperties of the fine structure of the hot gas and investigate its relationwith both the X-ray binary and globular cluster populations and with the AGNactivity.

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.
