289994 Astrophysical Magnetic Fields: Origin & Measurement (S) (SoSe 2018)

Inhalt, Kommentar

Ubiquitous magnetic fields are pervasive on all scales in the Universe, from
tens of kilometres in neutron stars, thousands of kilometres in planets,
millions of kilometers in stars through to thousands of light-years in galaxies
and several million light-years in the largest observable structures in the
Universe. Magnetic field plays a similar important role in the evolution of
all astrophysical objects as those in our daily life.

In this seminar course we will discuss about how magnetic fields are produced
and maintained in different astrophysical systems like stars, galaxies,
powerful jets launched from black hole accretion disks, and many more systems.

In order to glean information on the physical processes which generate magnetic
fields on astrophysical scales, it is equally important to measure them from
large telescopes on Earth. In the course of this seminar will also discuss about
the different techniques to measure magnetic fields and learn about the vast
cosmos in a little more detail.
