Title Solving the Mystery of Dark Matter with XMM-Newton


DOI 10.5270/esa-cm07j5a
Author Dr Michael Loewenstein
Description The sterile neutrino is a dark matter candidate that emits an X-ray through radiative decay. We initiated the first dedicated X-ray search for dark matter, deriving new constraints on sterile neutrinos from Suzaku data on the Ursa Minor dwarf spheroidal galaxy, and a marginal detection of a sterile neutrino line at 2.5 keV in the extreme dark matter dwarf spheroidal Willman 1. This tentative detection can only be tested with XMM-Newton EPIC. We propose 75-100 ksec observations (including offset pointings) of Willman 1, as well as Segue 1 and Ursa Major II. Confirmation by XMM-Newton would be of incomparable astrophysical importance, pointing the way to new physics, and implying that future X-ray spectroscopic missions will directly map the dark distribution and its evolution.

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.
