Distinguished Lecture: Unveiling the Dark Universe
Our cosmic inventory reveals that we inhabit a peculiar universe, which is dominated by invisible, dark entities: dark matter, dark energy and black holes. The bulk of the matter content of our universe is dominated by dark matter - comprising an inert, elusive and as yet undetected particle that likely formed in the early universe.
The measured accelerating expansion of the universe we believe is driven by dark energy, whose nature remains largely unknown too. While they scarcely contribute in terms of the overall mass budget, black holes appear to be littered throughout the universe, and were once believed to play a marginal role, now appear to fundamentally structure the visible universe.
In this talk, the speaker will discuss what we know and how we know the significance of these dark entities whose presence is revealed indirectly from multi-wavelength observations. She will review our current state of understanding focusing on the many intriguing open questions and future observations that will help unveil even more of the dark universe.
