The unknown nature of dark matter and dark energy stands at the forefront of research in modern cosmology.

Join us in Farrand Auditorium at the Santa Barbara Museum of Natural History for a free public talk on this captivating topic, presented by the Santa Barbara Astronomical Unit. No registration is required.

While several decades of investigation have provided strong observational support for the presence of dark energy and the existence of particle dark matter, we lack a detailed understanding of their origin and physical properties. University of Toronto Postdoctoral Fellow Daniel Gilman, Ph.D., will remotely address our in-person group on how we can use the visually-spectacular phenomenon of strong gravitational lensing to shed light on the nature of dark energy by measuring the expansion rate of the universe. He’ll describe how strong lenses act as cosmological laboratories for dark matter physics by revealing the spatial distribution of dark matter around galaxies.
