Prof. Gurzadyan about the Center for Cosmology and Astrophysics

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 recent studies include the modified gravity and observational indications, hyperbolic properties of photon beams and cosmic voids, the properties of supernovae and host galaxies, etc.

Among the recent studies is the performing of the high accuracy test of light speed invariance (Kennedy-Thorndike test) at European Synchrotron Radiation Facility (ESRF, Grenoble), participation in LARES satellite (ASI, ESA) program of testing of General Relativity and fundamental physics. The results were spread by international media and are now available in handbooks.

CONFERENCES
Reports at XXII Solvay conference in physics, General Assembly of International Astronomical Union, Swiss Biennial on Science, Technics + Aesthetic on “The Large, The Small and the Human Mind”, Sakharov conference (Lebedev Physics Institute, Moscow), the conference of Clay Mathematics Institute (Oxford) “The Mathematics of CCC“, etc.

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