| Description | We propose a 160 ks observation (4 times 40 ks mosaic) of the large scale gas corona around the nearby radio galaxy and late-stage merger Centaurus A. The Cen A group is the nearest relatively massive group ( M_Gsim 10 ^{13} M _odot ), and its large scale gaseous halo has not been previously studied because of its proximity. We will measure the temperature, density, and entropy of the gas and characterize its morphology to constrain the dynamics of the merger as well as the interaction between the gas and multiple epochs of nuclear activity to a distance of sim 50 kpc from the nucleus. The distribution and dynamics of the gas on scales of tens of kpc has played a key role in determining the morphology of the large scale radio structures. |

| 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. |
