Title Unveiling the enigmatic nature of the gamma -ray source 2FGL J1544.5-1126


DOI 10.5270/esa-z53h59v
Description Here we require a 30ks XMM pointing in order to unveil the nature of the enigmatic gamma -ray source 2FGL J1544.5-1126. This source was first supposed to be an AGN, hence an extragalactic object; however, X-ray and optical data revealed its galactic nature, but at present it has no clear classification. The proposed observation with XMM will allow us to reveal its emission properties thus clarifying its hidden nature.

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.
