Description An extended X-ray emission from the eastern radio lobe of Pictor A was discovered in AO1. The X-ray spectrum is well described by both a thermal and a non-thermal model.The X-ray emission could be produced by circum-galactic gas shocked by the supersonic expanding radio lobe or, alternatively,by IC of CMB photons by relativistic electrons in the lobe.If the X-ray emission is non-thermal,the magnetic field in the lobe is estimated to be significatively lower than the equipartition value. We propose to re-observe Pictor A for 50 ksec in order to:1)definitively establish the X-ray non-thermal-thermal nature of the radio lobe radiation and 2) check the equipartition assumption in the radio lobes.

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.
