Title Persistent shocks and feedback processes in the cluster VLSS J1431.8+1331


DOI 10.5270/esa-nh76cky
Author Dr Huub Rottgering
Description Recent simulations suggest that shocks in clusters have a long-lasting impact on the energetics and temperature distribution of the cluster gas. As a result all clusters should contain diffuse and filamentary regions with non-thermal particles that predominantly radiate at extremely low radio frequencies. Here we propose XMM-Newton observations of the best candidate for such a long-lived shocked system, the 74 MHz radio source VLSS J1431.8+1331, located in a cluster at z=0.16. The aims of the observations are to characterize the dynamical state of the cluster and to relate density and temperature variations to the radio structure. This will allow us to study the evolution of the energy content of both the thermal and non-thermal gas in the cluster on extremely long timescales.

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.
