Description
High resolution X-ray spectra are key to understanding the dynamics of hot gas. I will review some of the new results from the JAXA/NASA/ESA calorimeter XRISM/Resolve, which give the first high sensitivity/high resolution spectra above 6 keV. I will focus on the winds associated with accretion flows in strong gravity, the ultrafast outflows seen from Active Galactic Nuclei (AGN) which may be a major component of AGN feedback, controlling the starformation powered growth of the host galaxy. I will show how we get further insight into the launch processes by comparison to the very different winds seen from the stellar mass accretion flows and show how a new, larger area instrument will solve some outstanding issues in understanding the origin of these outflows.
