How do you measure a radial velocity?
Exoplanet discovery and characterization, and everything we know about the dynamics of the Milky Way, involves precise measurements of stellar radial velocities. That is not to mention absolutely everything in large-scale structure! I will talk about the hardware, software, and conceptual aspects of radial-velocity measurement, and try to give a sense of related projects that are in progress in my group.
