Title High-mass fossil clusters discovered through the SZ effect


DOI https://doi.org/10.5270/esa-e0i56vv
Author Dr Gabriel Pratt
Description We propose to observe two fossil clusters discovered in the Planck SZ survey. They are the first-ever fossil systems initially discovered via the SZ effect, and, with estimated masses M500 > 3.75 x 10e14 Msun, they are among the highest- mass fossil systems yet discovered. With these X-ray observations we will investigate their density, temperature, entropy and pressure profiles and compare with reference X-ray and SZ-selected fossil and non-fossil data. We will derive mass profiles and test for adiabatic contraction. As these objects are resolved in Planck, we will combine X-ray and SZ observations to investigate the pressure distributions in the outskirts.

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.
