THROUGH DARKNESS AND LIGHT: THE MANY FACES OF THE OUTFLOWS IN NGC 3783
NGC 3783 is the flagship Seyfert 1 galaxy for AGN wind studies. Its outflow has been studied extensively for the lower ionization components, but the highest ionized gas has barely been detected despite >Ms exposures with Chandra. A deep 200 ks exposure with XRISM, lasting 4 days, will yield the full velocity-resolved absorption measure distribution, from the lowest to the highest ionization stages. Its variability constrains its distance. Finding ultra-fast outflows or obscuration events, both transient phenomena, is another exciting opportunity.
