Title Turbulence in galaxy clusters - a new capability for the RGS


DOI https://doi.org/10.5270/esa-setp9os
Author Dr Jeremy Sanders
Description We propose to observe five moderate redshift cool core clusters to take advantage of a recently confirmed capability of the RGS instruments, to measure or place limits on the amount of turbulence in cluster cores. Our targets have bright cores and are at moderate redshift, so the degree of spatial broadening on the spectra will be low, and we will be able to measure or place tight limits on the velocity broadening in each object (less than 300 km-s). We will be able to place limits of 9--16 per cent on the fraction of turbulent pressure of the total pressure. An important secondary objective will be to study AGN feedback in luminous cluster cores. We will be able to determine whether AGN feedback matches cooling to better than 10 per cent.

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.
