Explore the story of gravitational waves and the cosmic collisions that create the elements we are made of through a weaving together of sound, art and astrophysics.  Through “multi-messenger” signals like kilonovae and gamma-ray bursts, discover how the cosmos communicates its most violent events. Blending scientific insights with creative expression, this talk reveals how listening to the Universe—and protecting its silence—can connect science, nature, and humanity.

Dr Karelle Siellez is an astrophysicist and lecturer at the University of Tasmania. A specialist in multi-messenger astronomy, she contributed to the first detection of a gamma-ray burst and gravitational waves from the same cosmic event, recognised with the 2017 Breakthrough Prize. She is also an award-winning science communicator who integrates art, sound, and storytelling into her work, making complex astrophysics accessible and inspiring. Karelle has lived and worked in France, the USA, and now Tasmania—where she divides her time between telescopes, classrooms, and the wilderness of sea and forest.
