Description We have recently identified the high-energy gamma-ray source 3FGL J1544.6-1125 as a candidate transitional millisecond pulsar binary in an accreting state. We request a deep exposure with XMM-Newton to: i) study the peculiar X-ray and optical variability patterns in more detail, ii) identify optical modulation at the orbital period and iii) search for coherent accretion-powered millisecond X-ray pulsations. Only XMM-Newton has the required capabilities to carry out this study, which would improve our understanding of the accretion physics of transitional millisecond pulsars and, by extension, magnetized objects, in general.

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.
