Millisecond Pulsars, Magnetars, and Black Holes: The Wickedly Cool Stellar Undead

The 9th Hintze Lecture delivered by Professor Scott Ransom The most massive stars burn the fastest and brightest and die spectacularly, exploding as supernovae and leaving behind some of the most fantastic objects in the Universe: neutron stars and black holes. These are fascinating objects themselves, but ever since Bell and Hewish discovered the first pulsar over 40 years ago, we've realized that we can use the neutron stars especially as powerful tools for basic physics and astrophysics as well. Specialized "timing" observations of the MSPs are providing a wealth of science, including new tests of general relativity, amazing probes of the interstellar medium, constraints on the physics of ultra-dense matter, new windows into the evolution of stellar systems both simple and complex, and the promise of a direct detection of massive ripples in space-time, gravitational waves.

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."
