XMM-Newton vs. Other X-ray Missions


The X-ray Multi-Mirror observatory is a significant step forward for the study of many astrophysical objects. The combination of exceptionally large effective areas with an imaging telescope, simultaneous observations of sources in the X-ray and UV/optical bands, simultaneous operation of the high-angular-resolution CCD (EPIC) detectors and high-spectral-resolution reflection grating spectrometer (RGS) in the X-ray band, and a long-period orbit allowing long, continuous observations of a single source provides unique opportunities to study the universe.

The following table compares various parameters of current and future X-ray observatories. The currently operational missions (XMM-Newton, Chandra, Rossi XTE , and Suzaku) are complimentary in their attributes with various combinations of effective areas, angular and spectral resolutions, and energy ranges. IXO, represents the next high throughput, high resolution X-ray observatory.

XMM-Newton area values (provided by Steve Snowden) are for an on axis source with a 30 arc second extraction radius (pattern 12 or less for the MOS, 4 or less for the PN). The MOS instrument areas give the combined area for both telescopes. The RGS values are for both telescopes. ROSAT, ASCA, RXTE, and ASTRO-E values taken from various HEASARC WWW pages. The RXTE PCA value is for layer 1.
