Title A high S-N multiwavelength spectral survey of PG quasars SSC_17


DOI 10.5270/esa-y3tp2os
Author Dr Michael Watson
Description GT-This is a high S-N multiwavelength survey of a complete sample of low-z, unabsorbed quasars, adding to existing data with simultaneous X-ray and UV spectra from EPIC and OM. The quality of the final dataset will allow us to address many important issues regarding the physics and structure of quasars. These include (1) the relationship between the hard X-ray continuum slope and the strength of the soft X-ray excess; (2) the relationship between both X-ray components and the physics of the broad and narrow line regions; (3) whether the optical-UV big blue bump and the soft X-ray excess are related; (4) the dependence of optical FeII blend strength on the hard and soft X-ray components. The targets for this project has been divided between the OM and SSC programmes.

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.
