This research line focuses on various aspects of galaxy formation and evolution. Both simulations and observations are used to understand how galaxies form and their properties evolve across the cosmological evolution of the Universe.

Specific topics

  • Development of theoretical models for studying the formation, growth and mergers of massive black holes within their host galaxies.  
  • Use of wide-area surveys to study active galaxies across redshift.
  • Use of hydrodynamical simulations to understand the formation of bar structures within galaxies and their role in shaping the global properties of the host galaxies. 
  • Study of globular cluster properties.
