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.
