Colloquium

Title: Neutrinos in Cosmology

Speaker:Jan Hamann, CERN

Location: Room 111, Physics Building

Time: 13:00-14:00, Wed, Sep 17, 2014

Abstract:
Even though neutrinos make up only a very small fraction of the energy density of the Universe today, they have a profound impact on its evolution. This allows us to deduce some of their properties from observations of, e.g., the cosmic microwave background (CMB) or the large scale structure. I will review the status of cosmological neutrinos after the release of CMB data from the Planck mission, and give an outlook on what we can expect to learn about them in the near future.

Biography:
Dr. Hamann is a theoretical physicist working in the field of cosmology.  He got his PhD degree from Hamburg University in 2004, and now working in CERN in Switzerland. Using a variety of high-precision astrophysical observations, he is looking for clues that help us better understand the history, composition and origin of our Universe.
