A Multi-wavelength MOCASSIN model of the Magellanic-type galaxy NGC 4449
Abstract
We use the photoionisation and dust radiative transfer code MOCASSIN to create a model of the dwarf irregular galaxy NGC 4449. The best-matching model reproduces the global optical emission line fluxes and the observed spectral energy distribution (SED) spanning wavelengths from the UV to sub-mm, and requires the bolometric luminosity of 6.25 × 109 L ☉ for the underlying stellar component, M dust/M gas of 1/680 and M dust of 2.2 × 106 M ☉.
