Modeling the Panchromatic Spectral Energy Distributions of Galaxies (1301.7095v1)
Published 29 Jan 2013 in astro-ph.CO
Abstract: The spectral energy distributions (SEDs) of galaxies are shaped by nearly every physical property of the system, including the star formation history, metal content, abundance pattern, dust mass, grain size distribution, star-dust geometry, and interstellar radiation field. The principal goal of stellar population synthesis (SPS) is to extract these variables from observed SEDs. In this review I provide an overview of the SPS technique and discuss what can be reliably measured from galaxy SEDs. Topics include stellar masses, star formation rates and histories, metallicities and abundance patterns, dust properties, and the stellar initial mass function.
