Analyzed redshift and magnification distributions of lensed sources.

Created model sky maps illustrating lensed source contributions.

Abstract

In the current paper we consider the prospects of observation of gravitationally lensed sources in far-infrared and submillimeter wavelength ranges by the future space telescopes equipped with actively cooled main mirrors. We consider the possibility of solving some of the important cosmological and astrophysical scientific tasks by observation of gravitationally lensed sources. The number counts of lensed sources for wavelengths from 70$\mu m$ up to 2000$\mu m$ were calculated. We discuss the distribution of lensed sources at different redshifts and magnification coefficients and also mass distribution of lenses. Model sky maps that illustrate the contribution of lensed sources were created.
