Title X-ray Observations of a SZ Discovered Cluster at z=1.45

Author Dr Bradford Benson
Description We propose to use XMM-Newton to observe an exceptional cluster at z=1.45 discovered via the Sunyaev-Zeldovich (SZ) effect by the South Pole Telescope (SPT). The cluster, SPT-CLJ2109-4626, is the highest redshift cluster yet discovered by SPT, with a Spitzer-optical red-sequence redshift of z=1.45. We predict that SPT-CL J2109-4626 has a mass of 4.0e14 M_sun, an X-ray temperature of 5.9 keV, and an X-ray luminosity of 9.8e44 ergs-s. These properties would place SPT-CL J2109-4626 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 60 ksec observation, enough to obtain 1500 X-ray photons, measure an X-ray luminosity and temperature, and to assess the dynamical state of this exceptional young 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.
