Andrew Fox is an ESA/AURA astronomer at the Space Telescope Science Institute (STScI) in Baltimore, Maryland. His research focuses on the study of gas in and around galaxies and its role in controling galactic star-formation rates. He is experienced in the use of spectroscopy to characterize diffuse astrophysical gas, particularly in the Milky Way and the Magellanic Clouds. He recently co-authored an invited review on the Magellanic Stream in the Annual Reviews of Astronomy and Astrophysics. Before joining the staff at STScI in 2011, he held postdoctoral fellowships at the Institut d’Astrophysique de Paris in France and the European Southern Observatory in Chile, and spent time as a visiting scientist at the University of Cambridge.Romeel Dave is a professor of astrophysics and South African National Research Chair in Cosmology based in Cape Town at the University of the Western Cape, the South African Astronomical Observatory, and the African Institutefor Mathematical Physics.  His interests include galaxy formation, circumgalactic and intergalactic gas, reionization, and cosmology.  His work employs supercomputer simulations to model the evolution of galaxies from the Big Bang until today, with the goal of understanding the wide diversity and global trends seen in galaxies and gas across cosmic time.  Before moving to Cape Town in 2013, he was a professor for 10 years at the University of Arizona, and held prior postdocs at Steward Observatory and Princeton University. Beginning in 2017 he will hold the Chair of Physics at the University of Edinburgh.

“Each chapter is written by a different author, a person very knowledgeable in the topic covered by their respective chapter and I was glad to see that very recent research was also included in the discussion … . I would recommend this book to someone seeking an in-depth overview of a topic covered in the book … .” (Electra Panagoulia, The Observatory, April, 2018)
