Research Interests of the group

Cosmology is the study of the universe as a whole. Its overall aim is to unravel the mysteries of the universe by scientifically addressing key fundamental questions. In particular, why is the universe structured today in the way that it is, how did it develop into its current form and what will happen to it in the future? Since humanity is also part of the universe, these questions apply equally to ourselves: where do we come from and where are we going?

We are strongly involved in numerous fundamental topics in modern cosmology.

  • CosmologyOfVeryEarlyUniverse
    • These are exciting times for early universe cosmology. The field is entering a new era where it is becoming possible to make detailed quantitative investigations into theoretical models of the universe's most distant past. This is of vital importance in view of the flood of data that will soon become ...
  • PerturbationTheory
    • Einstein's Theory of General Relativity is highly non linear. It is therefore very difficult to deal with all but the simplest situations using the full theory. Fortunately the universe appears to he homogeneous and isotropic to a remarkable degree, so the Friedmann LeMaitre Robertson Walker is adequate ...
  • PrimordialBlackHoles
    • Primordial Black Holes (PBHs) are black holes which may have formed in the very early universe when it was a fraction of a second old. PBHs are interesting because they can be small enough for quantum gravitational effects to be relevant, leading to their evaporation via the emission of Hawking radiation ...
