Overview

Updated edition of a popular introduction to cosmology, now with new observational data, supporting web material, and problems with solutions An Introduction to Modern Cosmology is an accessible account of modern cosmological ideas that enables readers to understand cosmology without resorting to the mathematical apparatus of general relativity. This fully revised Fourth Edition of the bestseller takes an approach which is grounded in physics with a logical flow of chapters, leading the reader from basic ideas of the expansion described by the Friedman equations to some of the more advanced ideas about the early universe. The Advanced Topic sections present subjects with more detailed mathematical approaches to give greater depth to discussions. Student problems with hints for solving them and numerical answers are embedded in the chapters to facilitate the readers' understanding and learning. The new edition contains updated observational data, more detailed explanations and examples of the central-to-cosmology Friedman equations, and references to extensive online supporting material. It also incorporates up-to-date results from the Planck mission, which imaged the anisotropies of cosmic microwave background radiation over the whole sky. Sample topics explored in An Introduction to Modern Cosmology include: The geometry of the universe, covering flat, spherical, and hyperbolic geometry, infinite and observable universes, and the three values of k Simple cosmological models, covering Hubble's law, expansion and redshift, particle number densities, and evolution including curvature The density of the universe and dark matter, covering galaxy cluster composition and brightness of the supernovae The origin of light elements in the universe, covering hydrogen and helium, problems with the Hot Big Bang, and flatness and horizon problems Written in a clear, concise format with short, accessible chapters, An Introduction to Modern Cosmology is an essential textbook resource on the subject for advanced undergraduate and graduate students of astronomy, astrophysics, and physics.

Author Information

Marina Cortês is Research Faculty at the Institute of Astrophysics and Space Science of the University of Lisbon, Portugal. She previously held positions at Lawrence Berkeley National Laboratory in the United States, Perimeter Institute for Theoretical Physics in Canada, and the Royal Observatory of Edinburgh in the United Kingdom. Her research spans observational and theoretical cosmology, including work on large-scale surveys such as SDSS-III’s BOSS and DESI, and on fundamental questions about the nature of time and the Universe. She won the inaugural Buchalter Cosmology Prize in 2014. Andrew Liddle is Research Faculty at the Institute of Astrophysics and Space Science of the University of Lisbon, Portugal. He held previous positions as Professor at the Universities of Edinburgh and Sussex, United Kingdom, where he was also Head of Faculty. He is interested in understanding the properties of the Universe and is best known for his work on cosmological models, in particular early Universe inflation.
