| Description | The origin of diffuse radio sources, so-called cluster radio halos and relics is still shrouded in mystery. The LOFAR Two-Metre Sky Survey of the 350 sq deg HETDEX field is breaking new ground in the study of diffuse radio sources as it shows diffuse emission in a large fraction of the SZ-detected clusters in that area. In particular, it has revealed diffuse radio sources in a number of low-mass clusters. While this field has good multi-wavelength coverage, there is relatively little X-ray data of the clusters that host this newly discovered emission. The aim of this proposal is to characterize the physical properties and the dynamical state of all Planck-detected clusters in this sample. |

| 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. |
