|Title||Multiwavelength observations of PSR B1259-63 periastron passage in 2010-2011|
|Author||Prof Andrii Neronov|
|Description||PSR B1259-63 is a unique binary system with a radio pulsar from which unpulsed X-ray, gamma-ray, and radio emission was observed. The pulsar is in a highly eccentric 3.4 year orbit around a Be star. Collision of the pulsar wind with the wind of Be star plays a crucial role in generation of the observed emission. The goal of this proposal is to investigate, for the first time, simultaneous X-ray (XMM-Newton) and GeV gamma-ray (Fermi) spectral evolution of the system as the pulsar passes through the Be star disk. Details of the X-ray-gamma-ray spectral evolution will allow to probe the physical mechanism(s) of particle acceleration and interactions during collision of relativistic pulsar wind with the wind from the massive star.|

|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.
