Specification of the research activity subject implemented within the research plan:
There are three important predictions of the Einstein gravitational theory in the limit of strong gravitational field that are closely related to quantum field theory and microphysics: inflationary cosmology, black holes, quark stars and neutron stars. We plan to study some problems related to these topics that are of crucial astrophysical interest because of the present observational data.

In the proposed project of the Institutional research we plan to continue our research in the field of Relativistic and particle physics and its application in astrophysics concerning three regions of problems that recently seem to be topical and widely discussed in the context of international research while being specific and unique in the context of research in the Czech Republic. The three areas of problems are the following:

1. Relevance of vacuum energy or quintessence in astrophysics and cosmology
2. Structure and properties of neutron stars and quark stars
3. Oscillation models of accretion disks

The solution of all these three regions of problems combine in a natural way General Relativity and Quantum Field Theory. In our research we plan to develop theoretical models by using both analytical and numerical approaches, express their link to observations, and make comparison with available observational data. We shall treat the data by the standard methods of the Fourier and wavelet analysis. We expect to evaluate sophisticated computational simulations of the astrophysical phenomena under consideration that will need highly advanced scientific computational methods, parallel computing, and visualization of the results by effective graphical methods. Therefore, we plan in collaboration of experts of the Department of Informatics and Department of Physics research in the fourth area of problems concerned on:

4. Advanced scientific computing and visualization

The methods of scientific computing will be directed to applications on the relativistic astrophysics problems presented above.
