Description In a recent radio survey of unidentified EGRET sources, we discovered two very unusual binary pulsars: PSRs J1614-2230 and J1744-3922. The first source, a 3.15ms binary pulsar with a companion too massive for standard binary evolution scenarios, may become the second known gamma-ray pulsar. The second source, a 172 ms pulsar in a tight 4.6 hr orbit around a low-mass companion, is likely unrelated to the coincident EGRET source. However, it displays bizarre radio emission behavior that may indicate transient accretion. This could be the long-sought "missing link" between accretion-powered and rotation-powered neutron stars. Here we propose to test both hypotheses using brief XMM-Newton snapshots. X-ray detection of either source would be very exciting.

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.
