Today I posted this tweet (below), which I think explains what happened today! I also gave a talk at MPIA Galaxy Coffee, with Adrian Price-Whelan (Flatiron), about the appearance of stellar parameters in the ESA Gaia XP spectral coefficients.
Seen on @katestoreyfish’s monitor rn. Is that a BARYON ACOUSTIC FEATURE in the @ESAGaia DR3 quasar sample?? #GaiaFete pic.twitter.com/0W0PPJd8H8
