摘要: The distortion of images faint high-redshift galaxies by the tidal gravitational field mass concentrations allows to investigate distribution individual galaxy clusters, investigation statistical properties in halos, and detection dark halos without any reference their luminosity. In addition, image on large scales can be used infer directly power spectrum cosmological density fluctuations find (dark) matter purely from properties. I will outline basic methods this new research extragalactic astrophysics, present several recent results; particular, a high-resolution map cluster is presented compared light distribution.
