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

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
