A Dust Emission Model for Very Young Galaxies: Expected Properties and Far Infrared Diagnostics

Abstract

Dust plays crucial roles in galaxy formation and evolution. In the early epoch of galaxy evolution dust is only supplied by supernovae (SNe). With the aid of a new physical model of dust production by SNe, we constructed a model of dust emission from forming galaxies. We show the evolution of the spectral energy distribution (SED). Then we adopt this model to a local starbursting dwarf galaxy SBS 0335$-$052. Further we discuss the SEDs of high redshift galaxies, and consider their observational feasibility.
