Description | Abell 1367 is an X-ray bright, nearby cluster containing an unusual set of small arc minute size clumps. Of the 16 clumps detected in Einstein and ROSAT observations, only 9 are associated with galaxies. Recent numerical simulations suggest that dense dark halos, formed at early epochs, can survive the cluster tidal field and halo-halo interactions. Perhaps the observed clumps are relics of these dense halos. We propose a 30ksec XMM observation that will cover the central region of the cluster and provide sufficient data to (1) accurately measure the spectra of individual clumps, (2) provide an accurate temperature map of the cluster on scales as small as 1 arc minute, and (3) for the brighter clumps, provide a spatially resolved temperature profile that will be used to |

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. |
