Title: Deconvolving the Fe Ka Line in NGC 2110
PI: J Turner
Approved Chandra Time (Ksecs): 100

We request simultaneous Chandra (100 ks) and XMM-Newton (50 ks) observation of NGC 2110. The combined data will allow us to tackle key issues which cannot be broached using either dataset alone. The primary goal of deconvolving the broad and narrow components of the Fe Ka line requires simultaneous observation by Chandra and XMM, as recent data have indicated narrow components of Fe Ka to vary. Thus, only simultaneous data will allow us to resolve the controversy regarding the diskline in type 2 AGN. The proposed data will also allow tight constraints on the absorbing gas.

Title:Simultaneous XMM-Newton and CXO/HETGS Observations of Seyfert 1 Galaxies
PI: I George
Approved Chandra Time (Ksecs): 60

We propose simultaneous XMM-Newton and CXO observations of two bright Seyfert 1 galaxies as part of a long-term programme to ensure that such observations are performed for the 20 brightest Seyfert 1 galaxies during the lifetimes of the missions. The targets, NGC 526A and MCG-2-58-22, were selected since they are the brightest members of the sample for which neither XMM-Newton nor CXO/HETGS observations have been made/scheduled with adequate signal-to-noise. The proposed observations will enable a number of important scientific issues to be addressed. For example, we will be able to decouple the narrow and broad Fe Kalpha line components: a crucial step in determining the real importance of relativistic effects close to the black hole.

Scientific Category: Clusters of Galaxies and Superclusters
Title: Mass content and dynamical state of 3 optically selected high z (z>0.8) clusters
PI: M Arnaud
Approved Chandra Time (Ksecs): 15

We propose to perform a joint XMM/CHANDRA/VIMOS follow-up program of three EIS distant clusters recently spectroscopically confirmed using FORS to be at z=0.81,0.94 and 1.14. We propose to observe with IFU of VIMOS the core of these clusters in order to measure their virial mass and study their dynamical state. The XMM/CHANDRA observations will be used to measure the X-ray mass and the morphology of the clusters. This will provide essential information on the physics of gravitational collapse and the relative settling of the gas and galaxies in the dark matter potential. Furthermore, the gas entropy in the core and the Lx-T relation will be compared with predictions of various theoretical models, providing greater insight on the physics that governs the ICM evolution.
