THE MAIN FIELDS OF MY INTEREST ARE RELATIVISTIC GRAVITATION AND
COSMOLOGY
My present efforts are
distributed in two main areas.
The first one is cosmology
more precisely the anisotropy of the CMBR (Cosmic Microwave Background
Radiation). In the last paper devoted to the mapping of the
CMBR and
search for anisotropy we announced the observation of the signal (Strukov et al., Pisma v Astron.
Zhur. and MNRAS (1992). Till present time I took part in interpretation of
observations in terms of primordial spectra and reconstration of
inflationary potential which govern the evolution of the early Universe
and produced spectra of primordial fluctuation.
Next topic is connected with gravitational lensing. The observation
of microlensing
events toward the Large Magellanic Cloud has led to discovery of a new population of our Galaxy
which consists of dark bodies with a mass of the order of $0.1\,
M_{\odot}$.
The nature of these objects is still unknown, though most reliable
hypothesis is that they are brown dwarfs. Other hypotheses include mirror
stars, black holes, and exotic stars which consist of cold dark matter
particles. The last hypothesis is attractive from the point of view of the
modern particle physics. It say that at least part of the dark body
population can consit of these objects. We discuss the opportunity of
explanation of the current observational data in the framework of this hypothesis.
Our conclusion is that current observational data indicate that
at least two events from seven events of OGLE data can be explained in the
framework of this hypothesis. The influence of this discovery will
be increased. Effects of weak microlensing will be important in
future high accuracy astromentric and VLBI observations. Some of my
papers I devoted to the phenomena.
