"Mapping the Universe with variable stars" by Dr Victoria Scowcroft

We're delighted that Dr Victoria Scowcroft of the University of Bath Physics Department, is able to join us to give us her amazing talk on Mapping the Universe with variable stars.

Since the discovery of the Leavitt law over 100 years ago, astronomers have used the unique properties of variable stars to map out the universe. In this talk Victoria will discuss how observations of Cepheid and RR Lyrae variable stars are used to study the structure and evolution of the Milky Way galaxy and its neighbours. Victoria will discuss how variable stars are used as the base of the “distance ladder”, and how they fit into the current debate around the “Hubble Tension” - the disagreement between different measurements of the Universe’s expansion rate - and the implications of the tension for cosmology and beyond.
