Abstract

Reducing radio data obteined by VLA observations we studied this cluster of glaxies as gravitational lens of radio-galaxies that lie behind it. With gravitational lensing we can reach distant sources that we could not reach in any other way because they are too faint. Thanks to the magnification given by the cluster we can reach and study them. Optical images of CL0024 show a ring of blue galaxies that lie at higher redshift; we studied radio maps of the central part of the cluster and compared them with optical and submillimeter images.
