摘要:

在本文中,我们认为,未来的空间望远镜配备主动冷却的主镜在远红外和亚毫米波长范围内的引力透镜源的观测的前景。我们认为解决一些重要的宇宙学和天体物理学的科学任务的引力透镜源的观测的可能性。计算了波长从70 $μm$到2000 $μm$的透镜源的数量计数。讨论了不同红移和放大系数下透镜源的分布以及透镜的质量分布。创建了说明透镜源贡献的模型天空图。

英文摘要:

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$μm$ up to 2000$μm$ 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.
