These proceedings provide a summary of the state-of-the-art in the understanding of physical processes which control galaxy formation. Many topics are discussed which present the latest observational results: dust extinction, the role of AGNs in the formation of massive galaxies, etc. How future instruments such as NGST, ALMA, FIRST, KMT and SKAI can help to resolve these questions is also addressed. The book will serve as a useful reference in the field for many years to come.

Pratiquement toutes les galaxies hébergent un trou noir supermassif en leur centre. Ces trous noirs croissent en masse en symbiose avec leur galaxie hôte et modèrent leur formation d’étoiles. Lorsque la matière est entraînée vers le noyau de la galaxie, un disque d’accrétion se forme, où le moment cinétique est transféré vers l’extérieur. Une énergie considérable est libérée lorsque la matière tombe dans le trou noir : c’est le phénomène des noyaux actifs de galaxie (AGN). Un noyau peut briller mille fois plus que la galaxie entière avec ses 200 milliards d’étoiles. L’activité nucléaire peut prendre de nombreuses formes, des quasars très puissants aux galaxies de Seyfert plus ordinaires, en passant par les radio-galaxies, qui peuvent lancer des jets jusqu’à dix fois le rayon de la galaxie. Noyaux actifs de galaxie examine toutes ces manifestations et présente une vue unifiée des AGN. Lorsque deux galaxies fusionnent, un trou noir binaire se forme et les deux trous noirs spiralent l’un vers l’autre pour fusionner, émettant des ondes gravitationnelles détectables par le futur satellite LISA.

The "European Yearbook" promotes the scientific study of European organisations and the Organisation for Economic Co-operation and Development. Each volume contains a detailed survey of the history, structure and yearly activities of each organisation and an up-to-date chart providing a clear overview of the member states of each organisation. In addition, a number of articles on topics of general interest are included in each volume. A general index by subject and name, and a cumulative index of all the articles which have appeared in the "Yearbook," are included in every volume and provide direct access to the "Yearbook's" subject matter. Each volume contains a comprehensive bibliography covering the year's relevant publications. This is an indispensable work of reference for anyone dealing with the European institutions.

Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is devoted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documenta tion of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, compared to which our system of accumu lating abstracts for about six months offers the advantage of greater convenience for the user. Volume 32 contains literature published in 1982 and received before February 11, 1983; some older literature which was received late and which is not recorded in earlier volumes is also included. We acknowledge with thanks contributions to this volume by Dr. J. Bou~a, Prague, who surveyed journals and publications in Czech and supplied us with abstracts in English.
