The Astrophysics of the Obscured Universe Across Cosmic Time

Dust changes our view of astronomical objects. It interacts with light from distant stars to make them more dim. Dust also radiates heat, which astronomers can see with millimeter and radio telescopes.

Early galaxies contained more dust, and that impacts our understanding of how galaxies form and change with time. The investigator will use multiple telescopes to understand how dust in the most distant galaxies affects the cosmos. Undergraduate students from underrepresented backgrounds will be trained in related astronomy research.

Dust makes up a negligible fraction of the mass budget of galaxies (
