• Simulations
    We run high resolution hydrodynamical simulations to investigate the dynamics of gas in clusters of galaxies and the intergalactic medium.
  • Galaxy Cluster Surveys
    Searching for and characterising clusters of galaxies - the most massive objects in the Universe.
  • Theoretical Cosmology
    Exploring the cosmological perturbations that lead to the large-scale structure, gravitational waves and magnetic fields in the Universe.
  • Pulsating Stars
    Resolving pulsation modes in hot sub-dwarf and white dwarfs to model their evolution and internal structure. We are also searching for brown dwarf planetary companions through study of evolved eclipsing binaries and pulsating stars.
  • Multiwavelength Astronomy

    Combining large datasets taken at multiple wavelengths, to maximise our understanding of the Universe.

  • Galaxy Evolution

    Understanding the formation and evolution of galaxies throughout the course of cosmic history.

  • Quasars

    Measuring the properties of luminous and distant Active Galactic Nuclei.
