Book Description
Progress towards an understanding of the dynamics and interactions of galaxies has been spurred on more than ever by a wealth of new observations and numerical experiments. The Heidelberg Conference 1989, the papers of which are collected in this volume, was extremely successful in presenting a synoptic view of the field in all its aspects: galaxy interactions in the early universe and in recent times, interactions of our galaxy and its neighbours, dynamical problems of elliptical and disk galaxies, groups and clusters, starburst and nuclear activity triggered by interactions, merger scenarios, and numerical experiments. Researchers and graduate students, specialists or not, will find here a complete overview of a rapidly growing field of astronomy.

Book Description
From the reviews: "Astronomy and Astrophysics Abstracts has appeared in semi-annual volumes since 1969 and it has already become one of the fundamental publications in the fields of astronomy, astrophysics and neighbouring sciences. It is the most important English-language abstracting journal in the mentioned branches. ...The abstracts are classified under more than a hundred subject categories, thus permitting a quick survey of the whole extended material. The AAA is a valuable and important publication for all students and scientists working in the fields of astronomy and related sciences. As such it represents a necessary ingredient of any astronomical library all over the world." Space Science Reviews#1 "Dividing the whole field plus related subjects into 108 categories, each work is numbered and most are accompanied by brief abstracts. Fairly comprehensive cross-referencing links relevant papers to more than one category, and exhaustive author and subject indices are to be found at the back, making the catalogues easy to use. The series appears to be so complete in its coverage and always less than a year out of date that I shall certainly have to make a little more space on those shelves for future volumes."

Book Description
This volume contains the written versions of the lectures given at the 26th course of the renowned Saas-Fee series. The book represents a comprehensive and up-to-date review of the field of galaxy interaction. Nowadays, galaxies are no longer seen as immutable objects: they evolve, interact, merge, blaze, and reshape. Dynamic forces can induce powerful stellar activity able to transform the matter composition and morphology of galaxies. The lectures included in this book aim at a better understanding of these remarkable and fascinating phenomena. Though the book is intended for graduate students and young post-docs in astrophysics, it contains more advanced and original material, as well as historical perspectives, which will be of great interest to experts and astronomy teachers also.

Book Description
As the second part of an ongoing investigation into the triggering of nuclear radio emission in inter acting galaxies, we present the results of a Very Large Array snapshot survey of southern interacting galaxies at 6 and 20 cm. The purpose of the survey was to search for and classify the nature of radio emission in a set of advanced-interaction disk galaxies which we had previously imaged optically. There were 42 interacting systems in our sample as well as 10 control systems, none of which had been previously detected by the Parkes surveys. Maps of the radio emission are presented and discussed. The radio properties of the galaxies are compared with their optical and infrared properties to determine the nature of the radio emission. We find that the radio emission in all our interacting galaxies can be attributed to processes associated with a burst of star formation caused by the galaxy interaction. In a specific case (0558-33), we quantitatively confirm earlier models of a starburst, but using radio observations to estimate the number of supernova remnants rather than optical spectra and broadband observations. In no case did we find clear evidence for a buried active nucleus. Further high resolution observations are needed however to better assess the contribution from any compact, weak active nuclei. Despite the obvious interaction these galaxies have undergone, none have developed into powerful radio sources, even though many of the most powerful radio sources are themselves the likely products of galaxy-galaxy interactions. We briefly discuss the implications for the triggering of nuclear activity.

Book Description
This book contains the proceedings of the sixth Eurographics Workshop on Vir tual Environments. The event took place from June 1 to June 2, 2000, in Am sterdam. We hope that readers will find these proceedings to be valuable, not only for virtual environment researchers, but also for practitioners developing or using virtual environment applications. We are glad to report that visibility of the workshop continues to expand and that virtual environment researchers and practitioners from allover the world are submitting papers. This year, 40 papers and case studies were submitted of which 20 were accepted. In addition, we are glad to see that the focus of the workshop is also expanding. We accepted 6 research papers on evaluation of virtual environments and there was a broad sampling of other topics. We would like to thank all those involved in organizing the symposium. In particular, thanks go to Mieke Brune who was in charge of the local organization. In addition, we want to thank the international program committee for their excellent, yet laborious, job in reviewing all submitted papers. The quality of the workshop is a reflection of the quality of the submitted papers and the quality of the reviewing process.
