SED modeling of the DustPedia galaxies using a Modified Black-Body (MBB)

Here we present the results from fitting the DustPedia galaxies with a Modified Black-Body model. The fit is applied to all available fluxes beyond 70 microns. The model assumes an emissivity of κλ=6.40 x (250/λ)1.790 cm2/gr adapted to the THEMIS model. Fluxes having major flags were excluded from the fit. 682 out of the 875 galaxies had sufficient data and could be fitted. A bootstrap analysis was used to calculate the uncertainties in dust temperatures, luminosities and masses. Results are presented in Nersesian et al. (2019, 624, 80).
