Michael Hilker Research

Since May 2001 I am a research assistant at the
Sternwarte (Observatory)
of the University of Bonn. Half of my
time I spend in the Satellite Project
DIVA, especially
in the
spectrophotometric aspects of this program. The other half of my time
I follow the research lines as listed below and participate in the education
and supervision of undergraduate and graduate students (see the available
diplomathesis
topics). Also I am a member in the
Graduiertenkolleg
about ``Galaxy Groups as Laboartories for Baryonic and Dark Matter''.
Before my position in Bonn I have been working as a post-doc in the
department of astronomy and astrophysics
of the Universidad Católica in Santiago
de Chile. My position there was granted by
FONDECYT (CONICYT) and my supervisor was
Prof. Dr. L. Infante.
My PhD thesis In February 1998 I completed my PhD thesis at the
Sternwarte Bonn in
February 1998. The subject of my thesis is: ``The center of the
Fornax cluster: dwarf galaxies, cD halo, and globular clusters'', supervised
by Priv.Doz. Dr. Tom
Richtler.
If you are interested in my PhD thesis use this link.
During my PhD research I was partly involved in the
Graduiertenkolleg about
``The Magellanic System and Other Dwarf Galaxies''.
Research Topics
Dwarf galaxy populations in the center of galaxy clusters and their
relation to extraordinary rich globular cluster systems and cD halos

Fornax Cluster)
