But the gas and stars are only the tip of an iceberg: a galaxy consists mostly of dark matter, which we know only by the pull of its gravity. The ages, chemical composition and motions of the stars we see today, and the shapes that they make up, tell us about each galaxy's past life. This book presents the astrophysics of galaxies since their beginnings in the early Universe. This Second Edition is extensively illustrated with the most recent observational data. It includes new sections on galaxy clusters, gamma ray bursts and supermassive black holes. Chapters on the large-scale structure and early galaxies have been thoroughly revised to take into account recent discoveries such as dark energy." "This book is self-contained, including the necessary astronomical background, and homework problems with hints. It is ideal for advanced undergraduate students in astronomy and astrophysics."--BOOK JACKET.=650  #0$aGalaxies.=700  1#$aGallagher, John S. $q(John Sill), $d1947-=970  11$l1 $tIntroduction $p1=970  11$l2 $tMapping our Milky Way $p58=970  11$l3 $tThe orbits of the stars $p110=970  11$l4 $tOur backyard : the local group $p151=970  11$l5 $tSpiral and 50 galaxies $p191=970  11$l6 $tElliptical galaxies $p241=970  11$l7 $tGalaxy groups and clusters $p278=970  11$l8 $tThe large-scale distribution of galaxies $p314=970  11$l9 $tActive galactic nuclei and the early history of galaxies $p365=980  ##$aJohn Gallagher is the W.
