→ Table of contents and schedule

Prerequisites:
Knowledge of the introductory astronomy lectures (MVAstro0 or WPAstro).

Exercises:
M.Sc. Fayezeh Shabani
Tue 16:00-17:00
ARI Seminarraum (1st floor), Mönchhofstr. 12-14
First tutorial: May 3rd; last tutorial: July 19th.
50% of homework points are required for being allowed to take the exam.
We issue homework sheets on Moodle every Wednesday afternoon. They have to be submitted the following week by Thursday, 17:15, either online or personally to us. They will be discussed in the next tutorial after submission.
The first homework sheet (issued April 20) is a recap of important points you should know from the introductory astronomy lectures; it will not be graded, but will be discussed on May 3rd.

Written exam:
Wednesday July 27, 15:00-16:15, ARI Seminarraum (1st floor)
50% of homework points are required for being allowed to take the exam. 50% of points need to be achieved in the exam to pass the module MVAstro3 (given successful participation in the seminar).
No calculator and no other tools or resources are allowed. Just bring your pens. We will provide sufficient paper for you.

Regular astrophysics colloquia:
→ Heidelberg Joint Astronomical Colloquium
→ ITA colloquium
→ ARI colloquium
→ Königstuhl Colloquium

Seminar of MVAstro3 – "Galaxies and their environment":
We will have 4 seminar Thursdays, each one starting at 17:15: May 12, June 2, 16, 30
ARI Seminarraum (1st floor), Mönchhofstr. 12-14
Successful participation requires regular attendance, apart from preparing and giving your own talk. Absence without excuse will be put on record. You should aim at a duration of 30 minutes, i.e. you need to carefully select what to present. Your talk should also briefly motivate the general relevance of the topic, and should contain a conclusion with the most important point(s) - the "take-home message". Feel free to contact us for availability of our seminar rooms if you'd like to rehearse your talk there.
