Title The X-ray nuclei of FRII radio galaxies: unification and accretion modes


DOI 10.5270/esa-lwg0b0a
Author Dr Martin Hardcastle
Description We have recently shown that a population of powerful radio galaxies, the low-excitation radio galaxies, appears to have no accretion-related nuclear X-ray emission, despite having high-luminosity radio jets: plausibly these objects are accreting via a different, radiatively inefficient accretion mode compared to the better understood narrow-line radio galaxies and quasars, and form a separate population in unified models. However, the crucial X-ray constraints came from a small, inhomogenous sample. In AO6 and AO7 we were awarded time for observations of a carefully selected sample of radio galaxies. We now propose to complete observations of this sample, allowing us to make definitive statements about the nature of the accretion mode in these objects.

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.
