NICER observation list: Target ID 559102

NICER has recently identified Ultrafast outflows (UFOs) with an enigmatic quasi-periodic variability of 8.5 days during an AGN outburst. The physical origin of these quasi-periodic outflows is unclear but time-resolved X-ray spectral analysis suggests that they are driven by quasi-periodic changes in the UFO's absorption. Motivated by the discovery of this new AGN phenomenon, we propose NICER monitoring (2x500 s for 150 days) of a future AGN outburst with an outflow. Our primary goal is to expand on the pilot study and build a sample to understand the frequency and duty cycle of such events. A large collecting area, good spectral resolution and the ability to monitor for months is necessary to achieve our science goal. As a result NICER is the only facility that can carry out this study.
