Title:Interstellar dust: what is it, how does it evolve, and what are its observational consequences?

Authors:Eli Dwek

Abstract: This paper reviews our current understanding of interstellar dust models, what constitutes a viable dust model, what observational constraints are essential for deriving such model, and the current viable dust models. Interstellar dust exhibits spatial and temporal variations, and the paper reviews the ingredients in constructing models for the evolution of dust, stressing the current uncertainties in the yield of dust from supernovae and AGB stars. Finally, the paper briefly describes the effect of dust evolution on the spectral energy distribution of galaxies, and, using a very simple criterion, present a rough estimate of the redshift when galaxies first become opaque.
Comments: 20 pages, 10 figures. To appear in the proceedings of: "The Spectral Energy Distribution of Gas-Rich Galaxies: Confronting Models with Data", Heidelberg, 4-8 Oct. 2004, eds. C.C. Popescu and R.J. Tuffs, AIP Conf. Ser., in press. New version includes a more accurate representation of eq. (7), an additional figure (10), two added references, and corrections for typos and style
