Course Description: Radio radiation
with a wavelength of kilometres to millimetres covers the
broadest wavelength range in the electromagnetic spectrum and,
like optical radiation, passes through the atmosphere almost
unhindered. While optical radiation mostly originates from the
surface of stars, radio radiation mostly originates from gas
between the stars, relativistic electrons and from the Big
Bang. It is almost undisturbed by dust and therefore allows us
to have a clear view of our Galaxy and others and to peek deep
into their centres. This specialized course will focus on the
role of radio astronomy in our understanding of the Universe,
from probing hydrogen gas and stellar evolution to
investigating energetic processes in quasars and the cosmic
microwave background radiation as the remnant of the Big Bang.
