How the Euclid Space Telescope Can Analyze Data on Sources Across the Sky

Gillis: We're working on getting the Euclid Space Telescope going so that it can analyze data on many, many sources across the sky to try to figure this out. And gravitational lensing is key to that process. By looking back through time, we can look at how the universe has accelerated through time. Gillis: There's an archive of talks we gave during the pandemic, coupled by me, many others by other people working there, which you can find online.
