Description We propose an intense monitoring campaign of the heavily obscured Seyfert Galaxy Markarian 3 during the XMM-Newton AO-13. We aim at: a) constraining the size of the gas clouds responsible for optically-thick reprocessing of the nuclear continuum; b) probing a hitherto poorly unexplored parameter space on the distance between the X-ray corona and the surrounding optically-thick gas. We request 10 observations of 17 ks each. Thanks to the unique combination of hard X-ray spectral shape and visibility, the proposed observations represent an extremely efficient way of using XMM-Newton during high-radiation intervals close to the perigee passages, when the feasibility of most astrophysical X-ray experiments is severely hampered.

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.
