Matthias Bartelmann

Matthias Bartelmann (* 1965 in Bamberg ) is a German physicist and professor at Heidelberg University . He works in theoretical astrophysics with a focus on cosmology and gravitational lensing .

biography

Bartelmann attended the Dientzenhofer grammar school in his native Bamberg . With the Abitur in 1984 he received the Bavarian gifted scholarship and was accepted into the Maximilianeum Foundation . Bartelmann studied physics at the Ludwig Maximilians University in Munich from 1985 to 1990 and graduated with a diploma . The topic of his diploma thesis was: The influence of a combination of micro and macro lenses on the statistics of cosmological objects . He went to the Max Planck Institute for Astrophysics in Garching near Munich to do his doctorate and received his doctorate in 1992 at the LMU on the topic of large-scale correlations of cosmological objects due to the gravitational lens effect . The work was awarded the Otto Hahn Medal by the Max Planck Society . Bartelmann worked for the next eleven years as a research assistant at the MPI for Astrophysics in Garching, with the exception of 1994 and 1995, when he did research in the USA at the Harvard-Smithsonian Center for Astrophysics in Cambridge , Massachusetts. In 1996 he received the Ludwig Biermann Prize for Young Astronomers from the Astronomical Society . Bartelmann completed his habilitation in 1998 on the subject of investigations into galaxy clusters using light deflection and X-ray emission (original title of the work: Diagnostics of galaxy clusters with light deflection and X-ray emission ) and received the Heisenberg grant in the same year . From 1998 to 2003 he was the scientific project manager of the German contribution to the Planck space telescope , a space probe for even more precise research into cosmic background radiation , which is intended to provide fundamental knowledge in cosmology. In 2003 Bartelmann was appointed professor of theoretical astrophysics at Heidelberg University , where he still teaches today. From 2006 to 2008 he was Dean of the Faculty of Physics and Astronomy. Among other things, he teaches theoretical physics, with a focus on theoretical astrophysics, general relativity , cosmology, gravitational lenses and background radiation.

research

The research areas of Bartelmann's research group for cosmology at the Institute for Theoretical Astrophysics at Heidelberg University overlap and partially complement each other. They include:

• The gravitational lens effect , especially the Einstein rings that occur with the strong gravitational lens effect . One focus here is on the
• Galaxy clusters . He also deals with the Sunjajew-Seldowitsch effect and magnetic fields in galaxy clusters.
• Cosmology , especially the structure formation of the universe and the role of dark matter and dark energy in it. Another focus - linked to the work on the Planck space telescope - is the cosmic background radiation and gravitational lens effects on it.

In addition to numerous scientific papers, Bartelmann also published popular scientific articles on his research topics in stars and space and in the Physik-Journal , the journal of the German Physical Society .
