Description PSR J1836+5925 had been known as 3EG J1835+5918, the brightest unidentified EGRET source, until Fermi LAT detected its pulsations with a period of 173 ms. With the spindown age of 1.8 Myr, this is the oldest non-recycled gamma-ray pulsar known. Previous X-ray observations have shown that its spectrum consists of thermal and magnetospheric components, but its X-ray pulsations have not been detected. To understand the multiwavelength properties of the pulsar emission, separate the thermal and magnetospheric components, measure the neutron star surface temperature, and assess the evolution of the thermal and nonthermal pulsar emission, we propose an observation with a high time resolution that will allow us to study X-ray pulsations at different energies and X-ray spectra at different phases.

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.
