Gravity & the Extreme Universe
Yacine Ali-Haïmoud’s research aims to understand the nature of dark matter, which permeates the Universe, and remains an unsolved mystery. He seeks out hints about what kind of new particle dark matter might be by studying imprints it may leave in the cosmic microwave background, the relic radiation emitted when the Universe was only 400,000 years old. Dark matter could also be made of black holes, and Ali-Haïmoud studies how gravitational waves, ripples in the fabric of spacetime, may test this hypothesis.
