| Description | Knowledge of the structure and kinematics of gas around supermassive black holes is vital to understanding accretion and thus AGN feedback. To this end, we, the AGN STORM 2 team, have been awarded a Large 198-orbit Hubble Space Telescope program and a Las Cumbres Observatory Key Project to measure reverberation lags in Mrk 817. Previous UV-optical reverberation mapping campaigns have successfully mapped the outer accretion disc and broad line region, but reveal that X-rays (thought to be the primary driver of multi-wavelength variability) do not correlate with longer wavelengths as well as expected. X-ray spectral and timing measurements are necessary to track changes in the geometry and dynamics of the inner accretion flow that likely affect our inference of the outer disc and outflow str |

| 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. |
