| Description | We propose to use XMM-Newton to observe an exceptional cluster at z = 1.47 discovered via the Sunyaev-Zel.dovich (SZ) effect by the South Pole Telescope (SPT). The cluster, SPT-CL J2040-4451, is the highest redshift cluster yet discovered by SPT, with a spectroscopic redshift of z=1.47. We predict that SPT-CL J2040-4451 has a mass of 5.6e14 Msun, an X-ray temperature of 6.0 keV, and an X-ray luminosity of 11e44 ergs/s. These properties would place SPT-CL J2040-4451 amongst the most massive known clusters at z > 1.4, and an important system to study the earliest forming massive clusters. We are requesting a 75 ksec observation with XMM-Newton; enough to obtain 2000 X-ray photons, and measure an X-ray luminosity and temperature of this young massive cluster. |

| 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. |
