Title XMM study of a sample of nuclear dust morphology selected Seyfert 2 galaxies


DOI 10.5270/esa-vwuwekp
Author Dr Matteo Guainazzi
Description Guainazzi et al. (1999, in preparation) recently discovered that the nuclear dust content and the optical reddening appear to be anticorrelated with the amount of X-ray absorption, leading to the suggestion that the absorbing matter in Compton-thin and -thick Seyfert 2 galaxies is qualitatively different. One of the most crucial correlation, nuclear dust versus Compton-thickness, is significant only at 1 sigma confidence level. We propose to enlarge the sample of objects for which high-resolution images of the nuclear region and X-ray measurements of the absorbing column exist, by observing further 24 objects with XMM. This will permit to establish this correlation, if true, at a confidence level >98. Total 205 ks of exposure time are requested.

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.
