Astronomy: Tools, Applications &
Who: U. Klein
When: Winter term, Tuesday 4:15 p.m., Thursday 4:15 p.m.
Where: AIfA, HS 0.03
This lecture is supposed to be attended by students studying main courses. Successful participation in the course on Theoretical Electrodynamics is a prerequisite; in addition, elementary courses in physics and mathematics are required. A successful participation in this class means 3 academic hours of lecturing per week, plus participation in the associated lab course. The latter usually takes place after the winter term (in a block).
Note that students in the Master of Astrophysics programme may perform this lab course as part of the advanced lab.
Any students who envisage a thesis in radio astronomy are strongly recommended to attend this lecture! In what follows a syllabus of the lecture is given, which is still subject to changes since it had to be 'glued together' from previously two courses.
