Principles of Radio Astronomy / Grundlagen der Radioastronomie
Vorlesung im Sommersemester 2022 (SS22), 2SWS, 2 Credit Points
Dozent:
Dr. Fabian Walter (MPIA)
Times:
This lecture will take place every Friday during the summer term, from
9:15-10:45am (dates below).
Location:
R106 / Philosophenweg 12
Registration:
Registration via email -- please contact walter@mpia.de
Language:
This Lecture will be given in English.
Credit points:
Required credit points can be obtained at the end of the term via oral examinations.
Outline:
In this lecture, we will discuss the principles of radio and
millimeter astronomy. This field is progressing rapidly, thanks to new
facilities that reach high sensitivities and resolutions, such as ALMA
and MeerKat. We will discuss the physical processes that give rise to
radio and millimeter wave emission, from star forming regions in the
Milky Way to galaxies in the very young universe. A focus will also be
the technology by which to capture radio and millimeter emission,
including the concepts of radio and millimeter interferometry. A short
outline is given below.
The physics behind radio astronomy
The electromagnetic spectrum from radio to sub-millimeter wavelengths
Radio and millimeter facilites: single dish telescopes and interferometers
Radio and millimeter instrumentation
Science applications, from the solar system to the cosmic microwave
background
Schedule:
All times are Fridays, 9:15-10:45am
