# Introduction To Cosmology

This course offers an introduction to astrophysical cosmology. Concepts of the expansion of the Universe, curvature of the Universe and redshift will be studied in detail. Topics explored include the Big Bang; inflation; primordial element synthesis; the cosmic microwave background; the formation of galaxies; and large-scale structure.

Introduction to Cosmology provides a rare combination of a solid foundation of the core physical concepts of cosmology and the most recent astronomical observations. The book is designed for advanced undergraduates or beginning graduate students and assumes no prior knowledge of general relativity. An emphasis is placed on developing the readers' physical insight rather than losing them with complex math. An approachable writing style and wealth of fresh and imaginative analogies from "everyday" physics are used to make the concepts of cosmology more accessible. The book is unique in that it not only includes recent major developments in cosmology, like the cosmological constant and accelerating universe, but also anticipates key developments expected in the next few years, such as detailed results on the cosmic microwave background.

Following the example of previous editions of the conference, also this year there will be open popular science lectures, to which the organisers cordially invite all enthusiasts of astronomy, astrophysics and cosmology. To meet the expectations of the audience, this year as many as two open lectures are planned. One lecture in Polish will be given by Prof. Marek DemiaÅ„ski, while the other, in English, will be given by Prof. Rien van de Weijgaert.

Cosmology is a branch of astronomy that involves the origin and evolution of the universe, from the Big Bang to today and on into the future. According to NASA (opens in new tab), the definition of cosmology is "the scientific study of the large scale properties of the universe as a whole."

Cosmologists puzzle over exotic concepts like string theory, dark matter and dark energy and whether there is one universe or many (sometimes called the multiverse). While other aspects astronomy deal with individual objects and phenomena or collections of objects, cosmology spans the entire universe from birth to death, with a wealth of mysteries at every stage.

You can read more about cosmology and the foundations of the Big Bang model in Wilkinson Microwave Anisotropy Probe's Introduction to Cosmology (opens in new tab) by NASA. For more answers to common cosmology questions, go to NASA's Ask an Astrophysicist (opens in new tab)page.

The Fourth Edition of Introduction to Cosmology provides a concise, authoritative study of cosmology at an introductory level. Starting from elementary principles and the early history of cosmology, the text carefully guides the student on to curved spacetimes, special and general relativity, gravitational lensing, the thermal history of the Universe, and cosmological models, including extended gravity models, black holes and Hawking's recent conjectures on the not-so-black holes.

This text is invaluable for undergraduate students in physics and astrophysics taking a first course in cosmology. Extensively revised, this latest edition extends the chapter on cosmic inflation to the recent schism on eternal inflation and multiverses. Dark matter is discussed on galaxy and cluster scales, and dark matter candidates are presented, some requiring a five-dimensional universe and several representing various types of exotica. In the context of cosmic structures the cold dark matter paradigm is described. Dark energy models include the cosmological constant, quintessence and other single field models, f(R) models and models requiring extra dimensions.

This course, taught in collaboration with the Computer Science Department, provides an overview of recent developments in quantum computation and quantum information theory. The topics include: an introduction to quantum mechanics, quantum channels, both ideal and noisy, quantum cryptography, an introduction to computational complexity, Shor's factorization algorithm, Grover's search algorithm, and proposals for the physical realization of quantum devices, such as correlated photons, ions in traps, and nuclear magnetic resonance. 3 hrs. lecture plus weekly seminar. A 10-unit version of the course, 33-658, does not include the seminar.

I have finished Carroll's general relativity book, Spacetime and Geometry. I am specifically interested in cosmology, so is there any book which goes more in depth into cosmology? I prefer a mathematically rigorous book, which goes beyond the cosmology chapter in Carroll's book. The Big Bang and inflation theory should be dealt with in depth.

As far as cosmology is concerned, the book which I consider to be THE best for a mathematical treatment of cosmology, is AK Raychaudhuri's "General relativity, astrophysics, and cosmology". It is excellently presented, Raychudhuri doesn't shy away from the math, and the old-school style makes it all the more elegant. So, I would STRONGLY recommend it.

I also suggest Narlikar's book on cosmology, it is beautifully written. As other users pointed out above me, Weinberg is also an excellent choice. In case you want an extremely mathematical book with astrophysics on the side, go for Straumann. But, for me, nothing beats Raychaudhuri's book. Good Luck!

Aside from the standard introduction to FLRW cosmology, inflation, thermodynamics etc, it covers an additional range of topics in cosmology such as the role of Modified Gravity, Models of Dark Energy, Anisotropic cosmologies and Inhomogenous models.

Steven Weinberg - Cosmology: Great book, it covers a lot of topics in a very rigorous way, at least for physicists, it can be hard to follow sometimes, as usual when talking about Weinberg this is not an introduction to the subject

Coles and Lucchin - Cosmology; the origin and evolution of cosmic structures: It's not a new book but it's one of the easiest introduction I know of. It's not complete and it's not up to date but the standard parts are very well written.

Viatcheslav Mukhanov - Physical foundation of cosmology: another great book in my opinion, differnt from the two mentioned above, more pedagogical than Weinberg, more physical than Lucchin, probably less complete than both, but a comparison on completeness is flawed cause they treat different topics. Surely worth read. I especially liked the chapters on inflation.

There's another book which I think could be very good for an expert physicist who wants to approach cosmology and astrophysics, it's by Tanu Padmanbhan and it's called Cosmology and astrophysics through problems. It's not an easy book at all, it's basically a book of exercises (some of them very hard) that builds complete knowledge of astrophysics and cosmology at least at a starring PhD level. There is a detailed solution for every exercise. There may not be many advanced research topics, but if you're able to go through the book you will surely have a solid base to start research in cosmology, I'd say more solid than a guy with a maser degree in these topics.

Daniel Baumann - Cosmology: you can find them here. These are the only lecture notes I know, and I think they are the best place to start studying cosmology. They are rather complete for an introduction and they are easy to follow. I like the structure and the approach in these lectures. 041b061a72
