Description The intracluster medium (ICM) of the Hercules A Cluster shows the imprint of a very energetic outburst from a central active galactic nucleus. The radio lobes of Hercules A appear to be driving a shock front into the ICM. A deep XMM-Newton observation would enable us to confirm that this is a shock front and to better quantify its properties by making accurate measurements of the temperature distribution. By examining the ICM on large scales, we can look for the individual and cumulative effects of earlier outbursts. The unusual X-ray cavities in Hercules A may have been created by shock heating of the ICM and we will attempt to detect the hot gas that should fill them if this is so. The data will also be used to measure the X-ray spectrum of the eastern radio jet.

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.
