Abstract We recently found an X-ray-emitting ejecta knot in the northeastern portion ofthe Galactic supernova remnant PuppisvirgulA, based on archival XMM-Newton MOSobservations. Interestingly, K-shell lines of the ejecta knot are possiblyblueshifted by 3400(2600-4400)km/s at the northern part and 1700(900-2400)km/sat the southern part. We here propose a 20ks RGS observation of this ejecta knotto perform high-resolution spectroscopy, and give stringent constraints on thepossible blueshifts. We also propose two 10ks MOS observations of the remnant.ssouthern region, where no X-ray CCD imaging spectrometer has been mapped despitesignificant emission was detected by a ROSAT all-sky survey. These observationswill first allow us to search for ejecta features and to obtain a complete X-ray view of Puppis A.

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.
