Dust and Interstellar Medium of Galaxies at High Redshifts
Abstract: Dust is one of the most mysterious components of galaxies. Although by mass it only represents ~1% of the interstellar medium, it has key roles in the physics and chemistry of the interstellar medium, has crucial roles in the star formation process, and hides a significant fraction of cosmic star formation across all redshifts. Despite its importance, our understanding of the properties of dust in galaxies at high redshifts is far from complete. In this talk, I will highlight our recent results using data from the Keck telescopes in Hawaii and the ALMA mm/submm array in Chile to set constraints on the dust attenuation and emission properties of galaxies at redshifts of z~1-3, the peak epoch of cosmic star formation activity known as Cosmic Noon. I will conclude the talk with a brief overview of the James Webb Space Telescope, its current state, and the revolutionary science that will be achieved by it in the near future, given its significantly higher sensitivity and resolution compared to those of its predecessors.
