Scientific paper

NGC 3516 shows a broad, redshifted iron K-line from the inner disk orbiting the central black hole. ASCA showed the profile to be variable and to have a narrow 6.4 keV core and an absorption feature at 5.8 keV. If confirmed, the 5.8 keV feature would be of major importance as it implies high velocity infall, which is rarely observed in AGN. We propose a 200ks HETG observation of NGC 3516 to confirm and constrain these narrow features around iron-K. We request simultaneity with our XMM GTO long-look, which will measure the broad component. Our HETG data will also detect numerous emission and absorption features from the warm absorber. Combined with our LETG and XMM/RGS data, we can build a complete picture of the highly-ionized, multiphase gas surrounding this AGN.
