Gaia EDR3

Today ESA Gaia EDR3 dropped! It was a fun day; the data are more precise and less noisy! I'm involved in a few different projects with the data. With Hunt (Flatiron) and Price-Whelan (Flatiron) I am looking at the local velocity-space structure in the disk, and seeing if we can classify features by looking at how they vary spatially around the Solar position. With Eilers (MIT) I am going to update our spectrophotometric distance estimates to APOGEE luminous red giants. With Bonaca (Harvard) I will find out if we can improve the kinematics and orbit identification of stellar streams. None of these projects got very far today, but we did make this visualization!
