Claire Lamman is part of a team of astrophysicists using data from the Dark Energy Spectroscopic Instrument to map as many as 50 million galaxies. In this talk, delivered in April 2024 at the annual Harvard Horizons Symposium, Lamman describes her distinctive contribution to this effort—gauging the “intrinsic alignment” of galaxies to better understand the universe and how it evolves.
