Starting from recent X-ray studies of sizable samples of local Seyfert galaxies at moderate and high energy resolution, I will address the following questions:
- Are the distributions of AGN wind physical parameters dependent on AGN luminosity or radio-loudness?
- How complete is our census of AGN winds? How many of them are we missing due to ionisation or inclination (or other) effects?
- UFOs in the post-Hitomi era: are we still seeking for an ultimate observational confirmation? Do observations of UFOs at high energy resolution support the finding at moderate (CCD) resolution?
- “Warm absorbers” vs. UFOs: two populations? Two aspects of the same underlying phenomenon?
- Are the different observational components of AGN outflows part of the same stratified flow? Are they independent components launched at different scales?
- What does the “ionisation gap” mean?
- Which observational constraints exist on the mechanism launching and accelerating the winds?
- Do AGN outflows contribute (or are responsible) for AGN obscuration?
- How uncertain are our estimates of mass/kinetic energy/momentum outflow rates?
- Bonus question (depending on the XRM status):
- Should XRM (X-Ray Re-flight Mission) fly, would the AGN wind observation plan originally designed for Hitomi still be adequate?
