“Extragalactic Astronomy and Cosmology is a textbook about what and how we know or hypothesise about the Universe and our Galaxy. The book starts out with a short overview of all the strange and wonderful astronomical objects and cosmological ideas that we face in modern science. I enjoyed most the depth and abundance of details provided in the book.” (AstroMadness.com, May, 2017)
“An obvious difference from many other roughly similar books is the large number of illustrations, many in colour. ... I recommend the book both to students and to those who work in fields other than those covered by the book ... . It is up to date, quite detailed for an introduction, and the numerous figures with references are particularly useful as jumping-off points to the original literature.” (Phillip Helbig, The Observatory, April, 2016)
