|Title||Exploring the X-ray emission from the unique ms-Pulsar PSR 1937+21|
|Author||Dr Werner Becker|
|Description||PSR B1937+21 is among the top brightest MSPs. Previous observatories like BSAX and XTE, however, allowed only a coarse characterization of its emission. Its pulse profile is double peaked with narrow pulses which are phase aligned with the giant radio pulses! Its spectrum is dominated by non-thermal emission. Timing analysis in different energy bands indicated that the pulsed emission is harder than suggested from phase integrated spectral fits. An unresolved ~40% DC component below 4 keV is indicated. PSR B1937+21 was for many years not observable by XMM due to satellite orbit constrains. We propose to explore its emission by performing a phase resolved spectral analysis in order to separate the different spectral components suggested to be present in the pulsar emission.|

|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.
