Illuminating the Universe Through Weak Gravitational Lensing

Question: How can we learn about matter that we can’t see? Answer: By looking at how the invisible matter’s gravity affects the matter we can see. This is gravitational lensing, an exciting and active field of cosmology research through which we hope to answer fundamental questions about the universe like the nature of dark matter and dark energy.  In this talk, I’ll focus on weak gravitational lensing: how it works, what It can tell us about the universe, and the prospects for up-and-coming weak lensing surveys with the Rubin Observatory and Roman Space Telescope.
