| Description | Sunyaev-Zel.dovich (SZ) surveys are currently the most powerful and consistent method of detecting high mass, high redshift galaxy clusters, whose dynamic, thermodynamic, and chemical properties serve as unique probes of the composition and growth of structure in our Universe. The Atacama Cosmlogy Telescope (ACT) has surveyed >13000 sq. deg of sky, and the resulting ACTPol survey has detected thousands of clusters (hundreds at z>1) based on their SZ signal. This proposal targets the most massive high-z ACTPol clusters without X-ray follow-up, allowing us to obtain detailed measurements of cluster masses, morphologies, and thermodynamic properties, while nearly doubling the number of X-ray observed clusters in this redshift range for which these measurement are possible. |

| 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. |
