| Abstract | The nearest pair of colliding galaxies, the Antennae, will be imaged ina deep 80ksec XMM EPIC observation. As a result the complex X-ray structure known from the ROSAT HRI, will be mapped at high S/N and to high energies. In many areas a true spectral/spatial data cube will be obtained. From this datacube: 1. The Super-Eddington sources can be studied via timing and spectra to study and test the existence of 10-100 Msol black holes. 2. The two starburst nuclei can have their component temperatures and abundances measured. The hard response of XMM will detect AGN power-laws, if present. 3. The X-rays from the star-forming HII regions can be factored into XRB and hot gas components. 4. Theextended gaseous tail emission can be mapped spatially and spectrally. |

| 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. |
