| Description | We propose to pursue the spectral survey of Broad Line Radio Galaxies proposed in AO1 through the observation of 2 new sources. Previous X-ray observations have shown that in BLRGs iron lines and reflections are weaker than in Seyfert 1s. This result suggests that either: 1) a non-thermal continuum possibly associated with the core radiation emission dilutes the Seyfert-like emission; or 2) the physical conditions of the accretion flow in radio-loud type I AGNs are different. Our first XMM-Newton observation (Pictor A) has revealed a cold narrow iron line and a very small UV bump, confirming the discrepancy with a Seyfert-like picture. More XMM-Newton observations are necessary to definitively establish the physical geometrical reasons of the BLRG-Seyfert 1 differences. |

| 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. |
