The XMM-Newton Guest Observer Facility

XMM-Newton, the X-ray Multi-Mirror Mission, is the second cornerstone of the Horizon 2000 program of the European Space Agency (ESA). XMM-Newton was launched on December 10 1999 at 14:32 GMT (09:32 EST). The observatory consists of three coaligned high throughput 7.5m focal length telescopes with 6 arc second FWHM (15 arc second HPD) angular resolution. With its large collecting area and X-ray and optical/UV bands, XMM greatly facilitates studies of objects ranging from clusters of galaxies to compact objects, and their inherent physical attibutes.

Besides having funded elements of the XMM-Newton instrument package, NASA also provides the NASA Guest Observer Facility (GOF) at the NASA/Goddard Space Flight Center (GSFC) and funds a Guest Observer (GO) program to support the usage of XMM by the U.S. scientific community. The GOF provides a clearing house for project-generated technical information and analysis software as well as budget support for U.S. astronomers who apply for XMM-Newton observation time.

• The US GOF plays a vital role in the compilation of the XMM Science Analysis System (SAS) and supports US GOs in their installation and use of SAS.
• The GOF has developed accurate and precise algorithms for modeling the EPIC particle background in the Extended Source Analysis Software (ESAS) SAS tools.
• The GOF continues to streamline data reduction.

XMM-Newton images over a 30 arc minute field of view with moderate spectral resolution. The European Photon Imaging Camera (EPIC) observes in the 0.2-12 keV band and consists of two MOS and one PN CCD arrays. High-resolution spectral information (E/dE~300 from 0.4-2.5 keV) is provided by the Reflection Grating Spectrometer (RGS) that deflects half of the beam on two of the X-ray telescopes. The observatory also has a coaligned 30 cm optical/UV telescope, the Optical Monitor (OM). More detailed information on the instruments can be found under Focal Plane Instrumentation in these pages and in the XMM-Newton Users' Handbook (GSFC or ESAC links).
