Abstract Chandra observation suggests that Fe distribution in the central region of thenon cD cluster A1060 is concentrated in small clouds with a scale of 10 kpc. Wepropose to evaluate the clumpiness in the metal distribution using thisisothermal non cD cluster, and derive the precise mass of metals in clusters.The RGS spectrum in the central region with lines from various elements show ushow this non-cD system has been enriched. We will also study the cause of thedark matter concentration in the core radius of 40 kpc based on the highsensitivity measurement of surface brightness and temperature. The nearlyisothermal gas with smooth morphology in A1060 gives us a unique opportunity foran unambiguous study for spatial fluctuations of metallicity and temperature.

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.
