We have discovered a new member of the rare and poorly understood class ofhigh-mass gamma-ray binaries: 3FGL J1405.4-6119. The system shows gamma-ray,radio and X-ray modulation on its 13.7 day period, with different patterns ateach waveband. The existing X-ray data, while clearly showing the period, areinsufficient to perform phase-resolved spectroscopy, which is needed toinvestigate the physics driving the emission and its orbital variability.

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.
