I have been teaching half of the astro847 Optical Observations class in the summer term of each year since 2013 (the other half was initial taught by Dr. Hendrik Hildebrandt and is now taught by Dr. Malte Tewes). In the class the students learn how to acquire, reduce, and analyse optical imaging data. It includes a lot of hands on work, which starts with taking observations with AIfA's telescope for two galaxy clusters. These data are subsequently reduced, calibrated, and photometrically analysed, with the goal to estimate the cluster redshifts from the multi-band photometry. The class also covers related topics such as the preparation of observing proposals, CCDs, and large-area imaging surveys.
I have also initiated, organised, and supervised an excursion for student from our class to visit the Observatorio del Roque de los Muchachos (La Palma) and conduct observations with the 4.2m William Herschel Telescope in October 2016 (see this report written by two of the students and page 35 of the forsch 1/2017 University magazine).
Furthermore, I am one of the organizers of the yearly AIfA teacher training and supervise one of the observational lab course experiments.
