1112.2942 (O. Ł. Karczewski et al.)

A Multi-wavelength MOCASSIN Model of the Magellanic-type Galaxy NGC 4449    [PDF]

O. Ł. Karczewski, M. J. Barlow, M. J. Page, S. C. Madden
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 6.25e9 Lsolar for the underlying stellar component, M_d/M_g of 1/680 and M_d of 2.2e6 Msolar.
