The Diagnostic Power of Dust - Lessons Learned from Galaxies
Abstract: Dust represents about 0.1% of the mass in baryons in galaxies today, yet it has a disproportionate impact on their physics and appearance. I will briefly discuss measurements of dust and dust effects in galaxies at different cosmic distances, and highlight what we understand and where the challenges and unknowns currently are. Recent observations from the recently launched James Webb Space Telescope are paving the way for answering some of the remaining questions.
