In this brief review I will touch upon the main points and trends of observational and theoretical cosmology, that influence and change today our understanding of the Universe.

New measurements of galaxy clustering and background radiations can provide improved constraints on the isotropy and homogeneity of the Universe on scales larger than 100 h Mpc. In particular, the angular distribution of radio sources and the X-Ray Background probe density fluctuations on scales intermediate between those explored by galaxy surveys and Cosmic Microwave Background experiments. O...

We propose a method for recovering the shape of the mass power spectrum on large scales from the transmission fluctuations of the Lyman-alpha forest, which takes into account directly redshift-space distortions. The procedure, in discretized form, involves the inversion of a triangular matrix which projects the mass power spectrum in 3-D real-space to the transmission power spectrum in 1-D reds...
