Main directions

Observational cosmology, large scale structure of the universe, dynamics of gravitating systems, dynamical systems in astrophysics, numerical experiments, modeling, data analysis

The studies in the Center (Cosmology group* in the Theoretical department since 1990),  were traditionally concentrated on the nonlinear problems of astrophysics and cosmology, with essential use of the methods developed in the theory of dynamical systems which  enable one to deal with chaotic and related instability phenomena from  rigorous positions. The number of performed studies range from the relaxation of the N-body gravitating systems and stability of the gravitating systems as of elementary catastrophes up to the instability of geodesic flows in the Wheeler-DeWitt superspace.

The observational discoveries of the last decades on the cosmic microwave background, indications on the dark energy, dark matter, baryon acoustic oscillations, large scale surveys,  etc  pose novel problems both on the analysis of the increased flow of information and its interpretation.  For example, the large scale galactic surveys, cosmic microwave background maps, other observational data enable to study the back-reaction of inhomogeneities on the propagation of photons and related observable effects in the perturbed Friedmann-Robertson-Walker universe. Observational indications on the massive black holes in the galactic centers led to the problem of the role of N-body chaos at the existence of a massive center.  Rigorous methods of the theory of dynamical systems appear rather efficient in these studies.

The general direction of the studies is orientated on the higher precision data at forthcoming observations and experiments, e.g. higher resolution and sensitivity cosmic microwave background maps, higher redshift galactic surveys to trace the Hubble diagram, X-ray surveys, etc.

Most of the current studies are performed via collaborations with noted centers.
