Abstract | We have just discovered the pulsar in the faint shell-type supernova remnant SNRG12.82-0.02, coincident with the TeV source HESS J1813-178 and possibly theFermi source 0FGL J1814.3-1739. PSR J1813-1749 is clearly one of the mostenergetic pulsars in the Galaxy, but its spin-down power is poorly measured. Weneed a brief follow-up observation to measure the all-important periodderivative, critical to determining the energetics, dipole magnetic fieldstrength, and spin-down age. This will allow us to infer the efficiency ofemission in all high-energy wavebands from X-ray through TeV, and to search forGeV pulsations with Fermi. We can also constrain the age of the SNR and thebirth period of the pulsar, important for modeling the radiation and evolution of the system. |

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. |
