Ultimas noticias sobre el sistema de lente gravitacional 0957+561.
Abstract
The gravitational lens system 0957+561 has been studied in detail.VLBI observations have allowed the author to determine detailed models for the lens. The models set useful limits on the value of Hubble's constant. The author is thus beginning to develop the applications of gravitational lenses as cosmological tools.
