Analysis of the effect of focusing of electromagnetic radiation by galactic microlenses in a wide long-wave range
2009
In accordance with contemporary notions, approximately at 96% of all mass of the Universe is invisible in the form of missing mass (23%) and dark energy (73%). Missing mass can manifest itself by means of interaction with electromagnetic radiation, which is created by gravitational fields of compact galactic bodies. As possible candidates for the role of microlenses, we examine substars, white dwarves, and main-sequence stars. We also take into account the fact that some of these microlenses may have the dense gas atmospheres. On the basis of model approximations, we have conducted an analysis of the focusing features of microlenses and have obtained numerical estimates for the coefficient of intensification in a wide long-wave range (from optical to radio). A multilateral investigation of the characteristics of an individual microlens is necessary to correctly interpret observation data.
