Description We propose to perform with XMM 2 repeated observations, at an interval of
months, of the Seyfert 1 galaxy Mkn 841 in order to measure its spectrum from
the UV to the medium X-ray range, disentangling the different spectral
components in the UV, soft X-ray and medium X-ray bands, and compare different
spectral states. XMM will allow also to determine the shape and variability of
the Fe 6-7 KeV emission complex, as well as the presence of other emission lines
predicted in ionized reflection models. We intend to combine these observations
with simultaneous BeppoSAX hard X-ray observations thus yielding the widest
spectral coverage obtained up to now for a Seyfert galaxy. These observations
are crucial to elucidate the origin of the UV and X-ray spectra and their

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.
