Here we require a 30ks XMM pointing in order to unveil the nature of theenigmatic gamma -ray source 2FGL J1544.5-1126. This source was first supposedto be an AGN, hence an extragalactic object; however, X-ray and optical datarevealed its galactic nature, but at present it has no clear classification. Theproposed observation with XMM will allow us to reveal its emission propertiesthus clarifying its hidden nature.

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.
