Title Search for type-2 quasars in narrow line radio galaxies


DOI https://doi.org/10.5270/esa-6txo4bk
Author Dr Paul O.Brien
Description We propose to observe five narrow-line radio galaxies, for which we predict that the 2-10 keV luminosity exceeds 1e+45 erg-s. With the null detection of optical broad line components, our sample makes an ideal set of candidates for type-2 quasars. XMM can measure the X-ray luminosity and absorbing column density accurately enough to obtain the first conclusive evidence for the existence of type-2 quasars, and also to investigate how commonly they occur in narrow-line radio galaxies. This observation will make an impact on our understanding of the circumnuclear environment of highly luminous AGNs, and will influence studies of the cosmic hard X-ray background.

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.
