Abstract | SGR 1627-41 is the only confirmed Soft Gamma-ray Repeater with a brightpersistent X-ray counterpart for which a rotational period has not yet beenfound. Only the high throughput of the EPIC/XMM instrument can provide thesensitivity to detect a periodicity down to a modulation level of a few percent.Timing information is a crucial element to study the physics of SGRs, isolatedneutron stars with super-critical magnetic fields. This investigation shall alsoprovide the highest signal to noise X-ray spectrum of this object. |

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. |
