Our group’s research interests range over the following areas:

  • Cosmology, galaxy formation, evolution and mergers,
  • Stellar evolution,
  • Properties of materials and the vacuum in ultrastrong magnetic fields,
  • Physics of white dwarfs, neutron stars and black holes,
  • Magnetic and relativistic stellar structure,
  • General relativity.
