A wide range of topics are covered, ranging from supernovae to active galactic nuclei, cosmic gamma rays to neutrinos and dark matter.

A fundamental, profound review of the key issues relating to the early universe and the physical processes that occurred in it.

The significance of the present IAU symposium, "e;The Large Scale Structure of the Universe"e;, fortunately requires no elaboration by the editors.

Galaxy groups and clusters provide excellent laboratories for studying galaxy properties in different environments and at different look-back times.

When my colleague Dr.

Since the last International Astronomical Union Symposium that dealt with matters cosmological, there have been dramatic advances, both on the observational and theoretical fronts.

The tremendous progress in astronomical observations over the past sixty years has revealed a vast structured universe whose fundamental parti- cles are galaxies, and clusters thereof.

The Milky Way Galaxy offers a unique opportunity to study the structure and contents of a major stellar system in three dimensions, at high spatial and spectral resolution, and to very large galactocentric distances.

A small country builds a world-class telescope in its backyard and lives happily ever after (or at least for a quarter century).

Scientists in the late twentieth century are not the first to view galaxy formation as a phenomenon worthy of explanation in terms of the known laws of physics.

The quantum and relativity theories of physics are considered to underpin all of science in an absolute sense.

'Gravity, a Geometrical Course' presents general relativity (GR) in a systematic and exhaustive way, covering three aspects that are homogenized into a single texture: i) the mathematical, geometrical foundations, exposed in a self consistent contemporary formalism, ii) the main physical, astrophysical and cosmological applications, updated to the issues of contemporary research and observations, with glimpses on supergravity and superstring theory, iii) the historical development of scientific ideas underlying both the birth of general relativity and its subsequent evolution.
