| Description | SDSS-C4 3028 is a cluster of galaxies identified in the Sloan Digital Sky Survey. It stands out as a nearby cluster containing a surprisingly large fraction of star forming galaxies, which is not fully understood in the standard model of galaxy evolution. It is also very unusual that the brightest galaxy of this cluster is a passive red spiral galaxy. We propose an XMM pointing that covers the entire cluster to determine its dynamical state and to obtain a more robust cluster mass measurement. We will also verify whether this passive red spiral galaxy is the brightest cluster galaxy residing at the the bottom of the gravitational potential of this cluster. SDSS-C4 3028 provides a valuable opportunity to study the evolutionary link between galaxies and clusters. |

| 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. |
