Observational Cosmology and the Formation and Evolution of Structure in the Universe

The evolution of galaxies: We seek to chart how galaxies have evolved over cosmic time, and to identify and understand those physical processes that have shaped their properties in different environments and at different epochs. A flagship project is zCOSMOS, a major redshift survey using 600 hours on the ESO VLT to obtain redshifts of approximately 30,000 galaxies in the COSMOS field, in the redshift range 0.1 < z < 3.5. The project is specifically designed to characterize the environments of galaxies in the distant Universe, from the 100kpc scale of the immediate group environment to the 100 Mpc scale of the cosmic web. A major focus at present is to identify the underlying simplicities of the galaxy population, today and at earlier times, and to use these to identify the phenomenological characteristics of the dominant physical processes involved.

The intergalactic medium: As an extension of our interest in the environment of galaxies, we are developing new ways to detect the intergalactic medium (IGM), the gaseous material between galaxies. Galaxies form out of the IGM and exchange material with it throughout their lives. We are currently working on detecting and characterizing galactic outflows through the study of metal absorption lines, and in detecting the extended filamentary structure of the IGM at high redshifts through fluorescent emission.

Magnetic fields in galaxies: The origin of galactic-scale magnetic fields is poorly understood, and their role in cosmic structure formation is unknown, and thus they usually ignored. We are trying to fill this gap by detecting magnetic fields in and around galaxies at high redshift.

Galaxies as cosmological probes: Very large samples of galaxies at different redshifts are increasingly being used as precision probes of the dynamical evolution of the Universe as a whole, especially to study the emergence of Dark Energy over the redshift interval 0 < z < 2. The ultimate success of this effort will require the detailed consideration of the evolving properties of galaxies. We have a continuing interest in exploring this aspect of cosmology, in collaboration with other groups at ETH.
