Beschreibungen
<P>Astronomers' Universe Series is a new series aimed at active amateur astronomers but is appropriate to a wider audience of astronomically-informed readers. The book provides an up-to-date account of active galaxies. Lists of such objects and their visual and imaged appearance in commercially available telescopes are an important component of this book. The book makes sense of the chaotic and apparently innumerable types of violently active galaxies. It provides the data and teaches the skills needed for users of small telescopes to observe and image some of these "galaxies in turmoil" for themselves.</P>
<P>Astronomers' Universe Series</P>
<P>The aim of this book is to provide an up-to-date account of active galaxies that is appropriate to the background knowledge of amateur astronomers, but might also be picked-up and read for interest by any reader with a scientific bent.</P>
<P></P>
<P>Active galaxies (including Quasars, QSOs, Radio galaxies, BL Lacs, Blazars, LINERS, ULIRGS, Seyfert galaxies, Starburst galaxies, N galaxies, etc.) are a major field of current astronomical research. Up to a fifth of all research astronomers are working on active galaxies. Huge amounts of time on major telescopes are devoted to their study. In almost all cases the galaxies are thought to be powered by 100 million solar mass black holes at their centres. </P>
<P></P>
<P>Some of the objects are bright enough to be seen in small telescopes, and an amateur astronomer with a 20 cm telescope and a CCD detector could obtain images of many more. Lists of such objects, and their visual and imaged appearance in commercially available telescopes are an important component of this book. This detailed but accessible work will be the only coherent and complete source of information for non-technical readers on an area of astronomy that fascinates many people and whose spectacular images from the Hubble space telescope, Gemini, VLT and other major telescopes frequently make the pages of the quality newspapers and occasionally appear on TV.</P>
<P></P>
<P>It also has the potential to be chosen as a set text or background reading for university courses on the subject, althought he writing style is such that it will appeal to all readers.</P>

<P>Introduction - What is a galaxy? - Galaxies in general - the difference between 'ordinary' and active galaxies.</P>
<P></P>
<P>The panoply of active galaxies: (Quasars, QSOs, Radio galaxies, BL Lacs, Blazars, LINERS, ULIRGS, Seyfert galaxies, Starburst galaxies, N galaxies, etc.) - what they are and what they do. (The images of many active galaxies are beautiful and spectacular, and the inclusion of a significant number of colour photographs is essential to the book.).</P>
<P></P>
<P>Active galaxies across the spectrum (activities and behaviours at radio, infrared, ultra-violet, x-ray and gamma ray wavelengths) </P>
<P></P>
<P>Explosions and jets - Multiple jets and why there is sometimes only one jet.</P>
<P></P>
<P>Faster than light - superluminal motions and how they occur.</P>
<P></P>
<P>The central black holes - Evidence for their existence - nature and properties of super-massive BHs - Jets and accretion disks - Energy sources - how BHs produce the features of active galaxies - how the BHs form.</P>
<P></P>
<P>Could the Milky Way become an Active galaxy? - and what would happen to life on Earth? - What will happen when the Milky Way and the Andromeda galaxy collide in 3,000 million years?</P>
<P></P>
<P>Observing active galaxies using small telescopes.</P>
<P></P>
<P>Observing data (positions, magnitudes etc.) for the brighter active galaxies.</P>
<P></P>
<P>Bibliography / web site list</P>

<P>Active galaxies involve some of the most extreme conditions and some of the most intriguing phenomena found anywhere in the universe.</P>
<P>Written for amateur astronomers, school and college science students and for those with a more general interest in science, Galaxies in Turmoil provides a readable, non-mathematical account of one of the hottest areas of astronomical research.</P>
<P>Observing details are given for 160 active galaxies, all of which are within the reach of amateur astronomers using small to medium-sized telescopes. There are tips on observing galaxies and active galaxies using binoculars and small to medium telescopes, along with a guide to imaging galaxies with CCD cameras.</P>
<P>Galaxies in Turmoil is equally suitable for practical amateur astronomers, or as a text for college courses including galaxies, active galaxies, quasars, deep-space objects and large-scale astronomy, up to the final year of an astrophysics, physics or science degree.</P>
<P>Research students - and even established research astronomers - will also find this book invaluable as a quick reference to the properties of, and phenomena within, those types of active galaxies that may be outside their specialisms.</P>

<p>Accessible to amateur astronomers who do not have a formal background in physics and math</p><p>Makes sense of the chaotic and apparently innumerable types of violently active galaxy</p><p>Shows how many of the apparently very different phenomena seen in deep space arise from a single cause</p><p>Explains how huge jets of material travelling at close to the speed of light can develop near black holes where normal expectations would be that material would be sucked into the hole - and shows why we sometimes see those jets travelling (apparently) faster than light</p><p>Provides the data and teaches the skills needed for users of small telescopes to observe and image some of these "galaxies in turmoil" for themselves</p><p>Includes supplementary material: sn.pub/extras</p>
<P>The new Astronomers' Universe Series is aimed at the same readership as the Practical Astronomy Series - active amateur astronomers. This book provides an up-to-date account of active galaxies which are a major field of current astronomical research - up to a fifth of all research astronomers are working on active galaxies. Lists of such objects and their visual and imaged appearance in commercially available telescopes are an important component of this book.
