Time and location:
Tuesdays and Thursdays 09:15-11:00
"Neuer Hörsaal" (nHS), Philosophenweg 12

Course content (short summary):
Concepts, technologies, and physical principles of modern observational techniques, along with their scientific applications. Includes optical telescopes and detectors, imaging and spectroscopy, characterisation of data, effect of the atmosphere, multiwavelength and particle astronomy.
→ Table of contents and schedule

Exercises:
Dr. Anna Pasquali
Mon 09:15-11:00 ARI SR   &   Tue 11:15-13:00 Phil 12 R 105
Tutorials begin on May 2nd/3rd. On June 13/14, tutorials will take place in the CIP-Pool Phil 12.
Homework sheets become available every Tuesday on Moodle and have to be submitted by Wednesday of the following week, either online or in person (e.g. at the Tuesday tutorial). We encourage solving and submitting the homework in groups; the maximum is 3 people. We do encourage online submission, but it is your responsibility that your submitted files are legible and have good quality; the same applies to handwritten sheets. It is also your responsibility to submit by Wednesday - not Thursday - and to make sure that your name is on the submitted sheet, even if someone else from your group is handling the submission. Submissions that don't carry the name of a person cannot be counted to the homework points of that person.
50% of homework points are required for being allowed to take the exam.

Prerequisites:
Knowledge of the introductory astronomy lectures (MVAstro0 or WPAstro).
Basic knowledge on electromagnetic radiation.

Important remark:
Credit points can be acquired either for MVAstro1 or for MKEP5, but not for both modules.
