| Abstract | Abell 1367 is an X-ray bright, nearby cluster containing an unusual set of smallarc minute size clumps. Of the 16 clumps detected in Einstein and ROSATobservations, only 9 are associated with galaxies. Recent numerical simulationssuggest that dense dark halos, formed at early epochs, can survive the clustertidal field and halo-halo interactions. Perhaps the observed clumps are relicsof these dense halos. We propose a 30ksec XMM observation that will cover thecentral region of the cluster and provide sufficient data to (1) accuratelymeasure the spectra of individual clumps, (2) provide an accurate temperaturemap of the cluster on scales as small as 1 arc minute, and (3) for the brighterclumps, provide a spatially resolved temperature profile that will be used to |

| 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. |
