Scientific paper
New improvements in extragalactic research have recently increased the number of sources at high redshift, i.e., QSOs and, especially, galaxies. Gravitational lensing/magnification events are more common among them, particularly because gravitationally magnified sources are preferentially selected in the flux-limited catalogs used to find distant sources. They offer a means of investigating the matter distribution from small scales (microlensing) to large scales (macrolensing). Recent observations and realistic mass distribution models of the arc-like structures (in A370 and CI 2244-02) make it possible to describe the observations well and to set new and independent conditions on the material content of the deflecting clusters; they also allow detailed studies of sources which are at the ends of the gravitational telescopes.
