This book is the third volume belonging to the series of proceedings of the Moriond Astrophysics meetings. I t follows "Cosmology and particles" publi shed in 1981 by les Editions Frontieres and "The birth of the Universe" whioh appeared in 1982 thanks to the same publisher. This workshop took plaoe on llBroh 1983 at La Plagne and as in 1981 and 1982 took advantage of the simultaneous presence of the particle physicists and the astrophysicists. As said in the title of the book the partioipa nts have presented their most recent views on the evolution of large structures and galaxies and the relevance of these questions on particle physics and cosmology. Among the llBny developments which are at the origin of the thirty five papers gathered here, three main themes have been touched on by several speakers during the workshop. They are (i) the influence of the mass of neutrinos and other "inos" predicted by the "Supersymmetry" theories, which are the more likely candidates for the hidden mass of the Universe, (ii) the dynamics of triaxial galaxies and (iii) the possible occurence of pregalactic stars with a debate on their hypothetioal nucleosynthetic role. Miny different views h3. ve been presented on these three topics (and many others) which prove the liveness of the physical cosmology.For the editor it has been quite difficult to find a reasonable and logical order to arrange the oontent of the book.
