Our Research

  • Study, modelling and visualisation of astrophysical processes in the vicinity of compact objects (black holes, neutron and strange stars), analysis of astrophysical data
  • Modelling of the inner structure of compact objects and their equation of state
  • Exploration of detailed influence of structure and induced spacetime of compact objects on their inner physical processes and processes in their vicinity
  • Simulations of observed X-ray variability and spectra of accreting compact objects considering existing and future X-ray observatories
  • Utilisation of advanced algorithms and hardware for parallel and accelerated computations and data processing

The centre established in 2013-2014 focuses on research in the area of complex modelling of astrophysical processes and observational data requiring complex linking of analytical and numerical methods. An emphasis is put on the development and utilization of advanced external as well as own software platforms benefiting from high power of currently available computers. Among the basic priorities of the centre are interpretation of existing satellite and terrestrial observations of radiation of compact objects and participation in preparing future astrophysical satellite missions. In parallel we also focus on applying the utilized methods in other areas of physics and applied physics, such as biophysics.
