A Multi-wavelength MOCASSIN Model of the Magellanic-type Galaxy NGC 4449
O. Ł. Karczewski, M. J. Barlow, M. J. Page +1
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…
