Cosmology from the Microwave Background

Physics Colloquium 22nd May 2015 delivered by Professor Jo Dunkley The Cosmic Microwave Background continues to provide us with a wealth of information about the universe. I will show new results from the complete Planck satellite mission, which mapped the microwave anisotropy in both temperature and polarization from 2009-13, and describe other recent progress from the Atacama Cosmology Telescope in Chile. I will discuss the status of the LCDM cosmological model, which is now so well established but has significant features yet to explain. I will describe some future directions for investigating the physics of the very early universe, and of the cosmic dark sector.

Om Podcasten

The Department of Physics public lecture series. An exciting series of lectures about the research at Oxford Physics take place throughout the academic year. Looking at topics diverse as the creation of the universe to the science of climate change. Features episodes previously published as: (1) 'Oxford Physics Alumni': "Informal interviews with physics alumni at events, lectures and other alumni related activities." (2) 'Physics and Philosophy: Arguments, Experiments and a Few Things in Between': "A series which explores some of the links between physics and philosophy, two of the most fundamental ways with which we try to answer our questions about the world around us. A number of the most pertinent topics which bridge the disciplines are discussed - the nature of space and time, the unpredictable results of quantum mechanics and their surprising consequences and perhaps most fundamentally, the nature of the mind and how far science can go towards explaining and understanding it. Featuring interviews with Dr. Christopher Palmer, Prof. Frank Arntzenius, Prof. Vlatko Vedral, Dr. David Wallace and Prof. Roger Penrose."
