Title: Supernovae and the Discovery of Dark Energy
Abstract: Just over 20 years ago, two teams of astronomers discovered that the expansion of the Universe is accelerating. This unexpected result was awarded the Nobel Prize for physics in 2011 and was based on careful measurements of Type Ia supernovae. The result implies that something, often referred to as Dark Energy, is pushing the universe apart. In this talk I will describe the work that led to the discovery of the accelerating expansion of the Universe, and the major projects that have taken place since then to improve, understand and explain the results. Finally I will discuss the exciting prospects for the future of supernova cosmology as new telescopes, which are being planned and constructed now, come into operation
These talks are open to everyone and are sponsored by the West Midlands Branch of the IoP.
