|Title||Spatial Structure of Overionized Plasmas in G346.6-0.2 and G359.1-0.5|
|Author||Dr Hiroya Yamaguchi|
|Description||We propose observations of the mixed-morphology supernova remnants (MM SNRs) G346.6-0.2 and G359.1-0.5, where presence of overionized plasmas was recently revealed by Suzaku observations. Although there are a number of similarities between the two objects, the measured abundances are largely different. The primary objectives of our proposed observations are to investigate the spatial distribution of the plasma parameters and abundances, and to resolve the entire plasma into ISM and ejecta components in each SNR. Accurate measurements of their ionization states provide a strong constraint on the origin of both overionization and peculiar morphology.|

|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.
