Help us get better by taking our quick survey! Your feedback will help us understand how we can improve in the future. Thank you for your time.Joining us this month is Dr Sandro Tacchella, Assistant Professor in Extragalactic Astrophysics at the Cavendish and the nearby Kavli Institute for Cosmology. Inspired by astronomy at a young age, Sandro pursued a degree in Physics and threaded a line between the “small” scale of planetary astrophysics and the statistical world of pure cosmology. He looks at the physics underpinning the formation of galaxies and black holes, hoping to understand how these cosmic structures came to be using data from some of the most advanced telescopes on, and above, Earth. His experience of using analytical and cosmological models to determine the physical properties of galaxies is being brought to bear on data from the recently activated James Webb Space Telescope’s NIRCam instrument, and he plays a key role in projects aimed at characterising the earliest galaxies.His research has taken him around the world, from Switzerland to Korea and the US, but he has still found time to start a family and maintain a healthy work-life balance. Today, we’ll talk to him about the benefits and unique problems he faces working in astrophysics, what it has been like to do cutting-edge research on three continents, and where he sees extragalactic astrophysics going in the near future.[00:36] – Guest’s intro[01:50] – Dreaming of space through a telescope[03:57] – Physics degree and outreach events to become a budding astronomer [05:03] – It's not so easy to do Astrophysics in Switzerland [06:00] – From broad astrophysics to extragalactic observations [08:17] – The exquisite images from the Hubble Space Telescope [10:00] – Why do galaxies lool like what they do today?
