Modelling the cosmos – with Claudia Maraston

How do we model the light of galaxies across the universe? Dive into the world of Stellar Population Models. Watch the Q&A, exclusively for our YouTube channel members, here: https://youtu.be/aTwNoo8im5M Subscribe for regular science videos: http://bit.ly/RiSubscRibe This talk was recorded at the Ri on 9 October 2023. These models observe the spectro-photometric and mass properties of galaxies, and have found widespread applications in astrophysics and cosmology, providing us with the tools to study galaxy formation and evolution both theoretically and through data interpretation. Claudia will explore how Stellar Population Models are developed, using leading-edge techniques to predict the properties of stars and their evolution over time. You'll discover how these models are used to study the formation and evolution of galaxies, shedding light on the mysteries of the Universe and its origins. Whether you're an astrophysics enthusiast or just curious, this talk promises to be a fascinating journey through one of the most exciting fields in modern science. So, join us as we unravel the secrets of the cosmos and explore the frontiers of our understanding of the Universe. ---- Claudia Maraston is the UK's top ranked female physicst. She is a Professor of Astrophysics at the University of Portsmouth. Claudia obtained her PhD in Astrophysics at the University of Bologna, leading to post-doctoral fellowships at the Ludwig-Maximillian University of Munich and the Max-Planck Institute for extra-terrestrial physics (MPE) in Garching (Germany). She was awarded a Marie-Curie fellowship in 2005 which she spent at the University of Oxford, before joining the University of Portsmouth in 2007 as the recipient of the Marie-Curie Excellence Team Grant. Claudia designs models for the calculation of spectro-photometric evolution of stellar populations, which are used as a tool to study galaxy formation and evolution both theoretically and through data interpretation. She is the winner of the 2018 Royal Astronomical Society Eddington Medal. ---- The Ri is on Twitter: http://twitter.com/ri_science and Facebook: http://www.facebook.com/royalinstitution and TikTok: https://www.tiktok.com/@ri_science Listen to the Ri podcast: https://podcasters.spotify.com/pod/show/ri-science-podcast Donate to the RI and help us bring you more lectures: https://www.rigb.org/support-us/donate-ri Our editorial policy: https://www.rigb.org/editing-ri-talks-and-moderating-comments Subscribe for the latest science videos: http://bit.ly/RiNewsletter Product links on this page may be affiliate links which means it won't cost you any extra but we may earn a small commission if you decide to purchase through the link.
