Professor Jacqueline van Gorkom delivers the 18th Hintze Lecture. How do galaxies get their gas and how do they lose it? Theories of galaxy formation predict that the growth of galaxies is regulated by the infall of hydrogen gas. This gas is the fuel for star formation. When galaxies run out of gas star formation stops. Interestingly, observationally we know much more about the stars in galaxies and how the star formation rate has evolved over time than we know about the gas. The gas is hard to observe. Currently a renaissance is taking place in observational radio astronomy, new telescopes have been developed, which can image this gas, and even better ones are being constructed. I will show what we already have learned, discuss remaining puzzles and outline what the future might bring.

The Role of Gas in Galaxy Evolution

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."
