PDF-(EBOOK)-An Introduction to Galaxies and Cosmology

This wellreceived textbook has been designed by a team of experts for introductory courses in astronomy and astrophysics Starting with a detailed discussion of our Galaxy the Milky Way it goes on to give a general introduction to normal and active galaxies including models for their formation and evolution The second part of the book provides an overview of cosmological models discussing the Big Bang dark energy and the expansion of the Universe This second edition has been updated to reflect the latest developments and observations while still probing the unresolved questions at the forefront of research It contains numerous learning features such as boxed summaries exercises with full solutions a glossary and a supporting website hosting further teaching materials Written in an accessible style that avoids complex mathematics and illustrated in colour throughout this text is suitable for selfstudy and will appeal to amateur astronomers as well as students.

At any given time we always think our Cosmology is correct: . Ancient: Earth is at center of Universe. Islands of Stars. Our goals for learning. :. How are the lives of galaxies connected with the history of the universe?. What are the three major types of galaxies?. How are galaxies grouped together?.

Written in simple and accessible language, this non-technical introduction to cosmology, or the creation and development of the universe, explains the discipline, covers its history, details the latest developments, and explains what is known, what is believed, and what is purely speculative. In addition, the author discusses the development of the Big Bang theory, and more speculative modern issues like quantum cosmology, superstrings, and dark matter.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life\'s most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundreds of key topics, from philosophy to Freud, quantum theory to Islam. This second edition has been updated and substantially expanded. Starting with the description of our home galaxy, the Milky Way, this cogently written textbook introduces the reader to the astronomy of galaxies, their structure, active galactic nuclei, evolution and large scale distribution in the Universe. After an extensive and thorough introduction to modern observational and theoretical cosmology, the focus turns to the formation of structures and astronomical objects in the early Universe. The basics of classical astronomy and stellar astrophysics needed for extragalactic astronomy are provided in the appendix.While this book has grown out of introductory university courses on astronomy and astrophysics and includes a set of problems and solutions, it will not only benefit undergraduate students and lecturers thanks to the comprehensive coverage of the field, even graduate students and researchers specializing in related fields will appreciate it as a valuable reference work.
