Our Research

The Research Centre for Theoretical Physics and Astrophysics (RCTPA) was established in 2013. In the period 2014-2018, its research activities were a part of activities of the Albert Einstein Center for Gravitation and Astrophysics supported by the Czech Science Foundation excellence grant No. 14-37086G.

Recent research activities of RCTPA are devoted into theoretical studies (based on combined analytical and computational methods) in relativistic physics and astrophysics and their relations with particle physics, testing results of theoretical predictions in general relativity or alternative theories of gravity with observational data from processes occurring in strong gravity of compact objects in the Universe, and into participation on theoretical studies related to the preparation of X-ray satellite missions. At the present period, the studies are focused on the following research areas:

  • Influence of large-scale magnetic fields on physical processes in the vicinity of black holes, neutron stars and quark stars, naked singularities, superspinars or regular compact objects, wormholes
  • Manifestation of alternative theories of gravity (branemodels, regular spacetimes, quintessential spacetimes) in physical processes taking place to vicinity of compact objects. Optical phenomena and quasinormal  modes of gravitational waves
  • Construction of accretion disk models in the framework of non-standard „dielectric“ perfect fluid toroidal configurations or configurations with matter governed by kinetic theory
  • Models of 1D string loops reflecting tension of magnetic fields in accretion structure and their astrophysical application
  • Influence of dark energy on accretion processes and their observational effects
  • Models of observational (optical) effects generated by compact objects strong gravity
  • Quantum gravity models 
  • Testing of quasiperiodic oscillation models on observation data from binary systems containing  black holes and neutron stars or from surroundings of supermassive black holes
  • Ringed accretion disk models
  • General relativistic models of polytrophic configurations and their astrophysical applications
  • Astrophysical processes in deformed Kerr metrics
  • Physical processes around magnetic black holes
  • Principle of minimal geometric deformation and generation of new exact solutions of Einstein's equations of General theory of relativity
