| Description | The nature of anomalous X-ray pulsars (AXPs) is one of the most important unsolved problems in Galactic high-energy astrophysics. AXPs are spinning-down pulsars with a soft X-ray spectrum, apparently not powered by accretion from a companion star, and with a luminosity larger than the available rotational energy loss of a neutron star. Two main models have been proposed to explain their behaviour: accretion from a residual disc or strong magnetic fields (i.e. magnetars). The aim of this proposal is to measure the optical pulsed fraction and broad-band spectrum using ULTRACAM+VLT and XMM, thereby placing the magnetar model of AXPs on a sound observational footing. |

| 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. |
