Beschreibung

The spectacular images of galaxy collisions capture the imagination. This book will show what is out there in the universe, what it's like in other galaxies, what they might look like, and how cosmic processes might affect life in other solar systems. It will explain crucial stages in the development of physical structure in the universe, and the effect of galaxy scale processes. Professor Struck will explore all the issues surrounding galaxy collisions. He will begin with a brief broad review of the background on galaxies, the history of their discovery, and how this has been driven by steadily improving technology. Chapters 2 gives details of the early stages of different types of galaxy collision - Rings of Fire, Tidal Swings and Retrograde and Sideways Reels - while Chapter 3 describes collisions between galaxies of very different masses: minor merger or dwarf destruction. Chapter 4 covers ultra-luminous infrared galaxies and major mergers and Chapter 5 briefly examines the techniques used for computer simulation results and how increasing computer capacity has affected the development of this field. The following chapter looks at understanding the physical processes of triggered star formation and nuclear activity. Chapters 7-9 look at the broader view of cosmological structure growth which determines the environment and conditions in which galaxy collisions occur. In the densest environments, this process repeats itself on the larger scale of galaxy clusters. The concluding chapter considers what a galaxy collision looks like from a solar system like ours. Although the galaxy is completely restructured and the night sky view would change greatly over the course of several hundred million years, the direct effects on our planet would be few and infrequent, with only a small probability of being truly catastrophic. These issues will be explored along with the ideas that galaxies must reach a certain evolutionary 'maturity' before they can even form solar systems, and that there are habitable zones within galaxies. Thus, galaxy scale processes, like collisions, can determine the fate of life on Earth-like planets.

Professor Curtis Struck has worked in the field of galaxy collisions since his graduate studies in the late 1970's. He has published more than 50 refereed journal papers, the majority in this area, and many as first author. He has spoken at a number of international research conferences and given many public talks. 

Struck is a theorist and computer modeler and has worked with many observers on the interpretation of data on colliding galaxies in all wavebands, except gamma-ray. This includes ground-based optical and radio data, and data from NASA's Hubble, Chandra, Spitzer, and GALEX space observatiories.

Klappentext

Galaxy collisions are the key process in building galaxies, triggering the formation of stars and the build-up of heavy elements that allow the formation of planets and solar systems. This book presents the revolutionary research advances achieved in the last decade and lucidly explains the underlying dynamical processes.

Galaxy Collisions

  • takes a comprehensive trip through the visually spectacular world of galaxy collisions;
  • investigates the interactions of stars, gas clouds, and dark matter in galaxy collisions;
  • uses analogies and metaphors to help comprehend the bizarre world of galaxies;
  • presents recent research results to enhance the understanding of galaxy formation and evolution;
  • includes discoveries of minor collisions within our own group of galaxies;
  • shows how a galaxy collision might affect a solar system, or a planet like ours.
