Sinopsis

It is sometimes said that astronomy is the crossroads of physics. In the same spirit, it can forcefully be argued that galaxies are the crossroads of astronomy. Internal pro ces ses within galaxies involve all of the fundamental components of astrophysics: stellar evolution, star formation, low-density astrophysics, dynamics, hydrodynamics, and high-energy astrophysics. Indeed, one can hardly name an observational datum in any wavelength range on any kind of celestial object that does not provide a useful clue to galaxy formation and evolution. Although internal processes in galaxies until recently occupied most of our attention, we now know that it is also vital to relate galaxies to their environment. How galaxies congregate in larger structures and are in turn influenced by them are crucial questions for galactic evolution. On a grander level we have also come to regard galaxies as the basic building blocks of the universe, the basic units whereby the large­ scale structure of the universe is apprehended and quantified. On a grander level still, we also believe strongly that galaxies are the direct descendents of early density irregularities in the Big Bang. Galaxy properties are now viewed as providing a crucial constraint on the physics of the Big Bang and a vital link between the macroscopic and microscopic structure of the universe.

Reseña del editor

This book is a collection of 50 review talks given in the morning sessions of the July 1986 Santa Cruz Summer Astrophysics Workshop on Nearly Normal Galaxies. The two-week workshop presented an up-to-date, comprehensive review of galaxy formation and evolution. This topic was given greater coverage than in any previous conference on galaxies. A unique feature of the workshop was the treatment of galaxy formation from the earliest density fluctuations in the early universe up to the latest phases of formation and evolution at present. Each carefully written review gives an up-to-date summary of an important aspect of galaxy evolution, including copious references and citations to current work. Professionals and graduate students alike will find this volume an invaluable summary of, and introduction to, the current literature. The book will also make ideal supplementary reading for graduate courses in galaxy formation and evolution.
