Abstract: Clusters of galaxies are the most massive objects in our Universe. Each of them contains dark matter, thousands of galaxies and is filled with hot intergalactic gas radiating in X-rays. Huge gravitational potential converts clusters of galaxies into excellent gravitational lenses able to amplify the light from very distant galaxies behind them.
