XMM-Newton Archive and Data Analysis
XMM Newton is a major joint ESA-NASA X-ray astronomy satellite with ESA responsible for construction of the satellite, mission operations and data processing , ESA nation states were responsible for the instruments
2 US groups have made substantial contributions to the instruments (Columbia Univ. S. Kahn PI for the reflection grating spectrometer (RGS) , UCSB F. Cordova PI for the optical monitor (OM)
The US guest observer program is supported by the guest observer facility (GOF) at Goddard Space Flight Center (R. Mushotzky US Project Scientist). This is also the site of the US archive
More than 120 papers accepted in refereed journals so far.
Despite considerable startup problems (ground segment and software) in the first 18 months XMM is in its operational phase, with most of the data going to the guest observer community worldwide (~1/4 is still going to GTO teams till Jan 2003)
