A fascinating talk explaining how the universe was created was given by Dr Stuart Muldrew of Leicester University at the observatory on the 7th October.

Our secretary, Marilyn has written the summary below of this excellent talk.

Dr Muldrew gave us an informative talk on his work modelling the universe.  He told us observations of galaxies are constantly pressing to new depths, giving us a series of snapshots in time after the Big Bang.  Ideally we want to understand how galaxies evolve, linking the observed snapshots to produce a galaxy family album.

To astronomers, computers are becoming equally as important as telescopes in explaining the Universe in which we live.  Building computer models of how the Universe evolves allows us to explain evolution between the different types of galaxies that we observe.  He showed us current predictive computer models and compared these with the actual data.  They were strikingly similar.

He told us of the key ingredients that go into building a computer model of the Universe.  He then used this to explain how galaxies trace the underlying dark matter distribution, and are affected by the energy released from their supermassive black holes and internal supernovae.

The talk generated many questions from members and Dr Muldrew commented afterwards that he had enjoyed the exchange.  We took him into the Dome and Sue gave him a potted history of our telescope and he was very impressed.

Our thanks to Stuart for his time and his excellent talk in which he conveyed complex concepts in a very clear manner.
