|Title||Structure of the Accretion Flows in Broad-Line Radio Galaxies|
|Author||Dr Michael Eracleous|
|Description||We propose to observe four of the X-ray brightest broad-line radio galaxies in order to investigate the differneces between the profiles of the Fe K lines of radio-loud and radio quiet AGNs. We will obtain spectra with very high signal-to-noise ratio with EPIC so that we can fit the line profiles with disk models and determine the range of radii in the disk where the lines originate. This constitutes a test of scenarios for the difference between radio-loud and radio-quiet AGNs since such scenrios predict different disk structures and by extension different line profiles.|

|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.
