NICER observation list: Target ID 462802

Abstract

Knowledge of the structure and kinematics of gas around supermassive black holes is vital to understanding accretion and thus AGN feedback. To this end, a multiwavelength reverberation mapping (RM) campaign on Mrk 817 has been built around an already-approved Hubble (HST) Large Program. This is a rare opportunity since it is only the second ~200 orbit HST RM campaign in its 30 year lifetime. Previous RM programs have mapped the accretion disk and broad line region, but revealed that X-ray flux correlates poorly with longer wavelengths. This is a conundrum, since X-rays are thought to drive the multi-wavelength variability. We propose NICER monitoring every other day throughout to track the X-ray spectral changes (rather than just flux changes) and probe the X-ray/UV/optical connection.
