| Abstract | SDSS-C4 3028 is a cluster of galaxies identified in the Sloan Digital SkySurvey. It stands out as a nearby cluster containing a surprisingly largefraction of star forming galaxies, which is not fully understood in the standardmodel of galaxy evolution. It is also very unusual that the brightest galaxy ofthis cluster is a passive red spiral galaxy. We propose an XMM pointing thatcovers the entire cluster to determine its dynamical state and to obtain a morerobust cluster mass measurement. We will also verify whether this passive redspiral galaxy is the brightest cluster galaxy residing at the the bottom of thegravitational potential of this cluster. SDSS-C4 3028 provides a valuableopportunity to study the evolutionary link between galaxies and clusters. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
