Abstract Double-double radio galaxies (DDRGs), in which two epochs of jet activity can beobserved in a single object, are very important for investigating many aspectsof radio-galaxy physics including particle content, source dynamics,environmental impact and duty cycles. We request XMM observations of 3 DDRGs, inorder to detect inverse-Compton emission from their radio lobes and thermalemission from their surrounding hot-gas. This will allow us to measure both theinternal pressure from the relativistic plasma, and external pressures acting onthe outer lobes, which are no longer fed by the jets, and are expected to be inpressure balance. We can therefore investigate the presence of heavy particlesin the outer lobes, which may be crucial for the inner lobe confinement.

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.
