Cosmology and extragalactic astronomy

Cosmic Microwave Background Radiation

• Theoretical work:
  • Physics in the very early Universe including structure formation
  • CMBR polarisation
  • Simulations of removal of Galactic and extragalactic foregrounds in CMBR observations
• Observational work through involvement in the TopHat balloon-experiment and the planned ESA space mission Planck

Clusters of galaxies

• High-redshift X-ray clusters (XMM LSS)
• ESO Imaging Survey clusters
• Dynamical properties of cluster cores
• Gas, stars and dust in cluster centres

Gamma Ray Bursts

• Localization and properties of GRB afterglows
• Use of GRBs as cosmological probes
• GRB host galaxies
• HETE-2, INTEGRAL, Swift follow-up

Galaxies

• The fundamental plane for galaxy clusters: The surface brightness test for the expansion of the Universe
• Galaxy evolution
• The high-redshift Universe

Gravitational lensing
