Content
The physics that drives galaxy evolution operates on a large dynamic range of spatial scales and across a wide range of gas phases. The unique perspective enabled by high-resolution radio continuum, polarimetric, and spectral line observations offers important insights not possible in other parts of the electromagnetic spectrum. I will present several examples of this, where SKA precursors/pathfinders are delivering results that require a VLBI perspective to understand fully, ranging from AGN-driven HI outflows in nearby disk galaxies to the highest redshift hydroxyl megamasers known, deep extragalactic legacy fields and dual/binary supermassive black hole candidates. I will give an update on several VLBI programmes that provide a more complete picture of galaxy evolution physics, demonstrating the importance of the high resolution radio perspective in achieving the SKA galaxy evolution key science goals.
