摘要
Gravity is the key engine for the evolution of the universe and the formations of its main structures: galaxies, clusters of galaxies and filaments. Gravity is also an invaluable tool for exploring the universe through the relativistic effect of gravitational lensing. The gravitational potentials of clusters of galaxies turn these bodies into powerful cosmic telescopes which enhance the signal from high-redshift galaxies. In this paper we present a project to study such galaxies with the Gran Telescopio Canarias (GTC) and the instrument OSIRIS. We describe the gravitational lens effect, stressing the strong regime case in clusters of galaxies. Then we show an application of the numerical codes to study the cluster MS2137.3-2353. Finally, we discuss the use of the Large Millimeter Telescope (LMT) to find candidates for lensed galaxies at very high redshift.
