Abstract	At a distance of <40 Mpc, the Antlia cluster, centered on the massive ellipticalgalaxy NGC 3268, is the nearest non-cool-core cluster. Antlia also contains asubcluster, centered on another massive elliptical galaxy NGC 3258, residing 250kpc southwest of the main cluster. We propose one 20 ksec XMM observation of NGC3258 and one to its southwest side, complementing the existing observation ofthe main cluster. Together, these cover the intracluster medium over a span of500 kpc. The requested observation would allow us to shed light on the origin ofnon-cool-core clusters via resolving the merging scenario between the twosystems and to study the X-ray properties of its member galaxies.

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.
