PDS456
PDS 456 is host to the archetypical ultra-fast outflow (UFO) observed through its blue-shifted (0.25c and higher) H-like Fe absorption trough. This UFO is both of high statistical significance and per- sistent; it has been observed several times both in the Fe-K and in the soft X-ray band. Resolve will be able for the first time to measure the velocity profiles of the absorption lines, and in the ideal case their inner kinematic structure, which will shed light on the physical nature of the wind. The high throughput of Resolve in the ideal case will further allow to measure the variability of the UFO over shorter time scales than ever before.
