Some of the biggest mysteries in the universe are also the hardest to see. Join Dr Niamh Fearon as she explores the world of dark matter—the invisible substance thought to make up 85% of all matter in the cosmos. From deep underground labs to cutting-edge detectors, learn how physicists are working to uncover the true nature of this elusive material.
Digging for Dark Matter: Searches for the most elusive particles in the Universe
Niamh Fearon
(Postdoctoral Research Assistant, Department of Physics)
Niamh Fearon is a Postdoctoral Research Assistant working at the Particle Physics Department, University of Oxford in the field of direct detection of dark matter. Whilst dark matter is estimated to account for 85% of matter in the Universe, its particle nature is unknown. This talk will detail current terrestrial experiments searching for particle dark matter including the LUX-ZEPLIN and DarkSide-20k experiments.
The James Webb Space Telescope: a $10 billion technological marvel transforming our understanding of the Universe.
Aayush Saxena
(Postdoctoral Researcher in Astrophysics, Research Associate in Physics at St Peter's College)
Aayush is a member of the James Webb Space Telescope instrument science team, primarily focusing on understanding the origins of stars and supermassive black holes in some of the earliest galaxies that formed after the Big Bang. The key questions his research aims to answer include where galaxies like the Milky Way come from, and how the physical and chemical conditions evolve in the Universe to create stars like our sun, and planets like our Earth.
