[78.04] Modeling UV-FIR SEDs of Starburst Galaxies with DIRTY

K. A. Misselt (NASA/NRC), K. D. Gordon (Steward Obs), G. C. Clayton (LSU)

We apply the DIRTY model to a small sample of nearby starburst galaxies. The DIRTY model is a three-dimensional Monte Carlo radiative transfer code. The model self-consistently includes dust heating and emission, fully accounting for the effects of the transient heating of small grains. Dust self-absorption is also accounted for by treating photons emitted by the dust as an additional heating source and adopting an iterative radiative transfer scheme. The UV to far IR SEDs of the galaxies are well reproduced using DIRTY, and quantitative information including star formation rates, dust masses, and dust temperatures are derived. The ability to accurately reproduce the full SED of starburst galaxies is discussed in the context of modeling galaxies at high redshift.
