| Description | The primary X-ray emission observed in AGN is believed to be produced from a tiny region surrounding the SMBH, namely the corona. A critical coronal compactness versus temperature threshold is predicted above which any increase in the source luminosity would then generate positron-electron pairs rather than continue heating the coronal plasma. Current observations show that all local AGNs populate the region below this critical line. However, these models have rarely been probed in the high-luminosity regime where the tightest constraints can be made on the coronal models. Here, we propose four high-luminosity quasars (zvirgul1-2) to more than double the current sample size of high-luminosity quasars to further constrain the coronal models and thus better understand the physics of coronae. |

| 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. |
