|Title||Deep X-ray view of the bare nucleus Seyfert Ark120: unveiling the core of AGN|
|Author||Dr Delphine Porquet|
|Description||[truncated] We propose here a deep XMM-Newton observation (4 x 120 ks) of Ark120 -- and a joint 120ks Chandra-HETG observation to measure the narrow FeK line core -- to establish the origin of the soft excess (Comptonization or blurred reflection), its accretion disk properties and its black hole spin. If the soft excess originates from blurred reflection off an ionized accretion disk, we will be able to clearly detect and resolve, for the first time unambiguously in a BLS1 AGN, broad soft X-ray lines (e.g., OVII, OVIII and FeL). It will be the first very high S-N X-ray observation of a bare AGN.|

|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.
