Reading Seminar on Synthetic Spectra

From December 2021 till March 2021, Jack Davies and I ran a reading seminar on synthetic spectra. Our goal is to study the basics of synthetic spectra and discuss some of its applications. You're welcome to contact me or Jack if you are interested in participating the seminar.

Time and Location

The seminar will take place weekly on Mondays on Microsoft Teams. You can find the concrete time slot (CET) for each talk in the schedule below. Please contact Jack Davies or I if you want to be added to the MS Team.
