Abstract:
Cosmic dust plays an important role in galaxy evolution, providing chemically active regions to rapidly produce the base ingredients for new cycles of star formation. At the same time, this dust screen obscures over half of our view of cosmic star formation and our view of the bulk build up of stars across cosmic time. In this talk, I discuss the new insights of the dust obscured universe in the cosmic noon and dawn. With high resolution imaging of dusty galaxies at redshifts 2 to 5, I show the surprising diversity in dusty galaxies that are likely the progenitors of giant elliptical. A surprisingly warm lyman break galaxy at redshift 8 furthermore complicates our view of early dust build up, and by probing the limits from over 200 hours of ALMA time at z 8 to 15, I detail our best attempts at finding the start of dust emission in the Universe.
