The embedded super-star cluster of SBS 0335-052

Abstract

SBS 0335–052 is the second most metal-deficient galaxy known, with Z⨀/41 (Izotov et al., 1997). Even though SBS 0335–052 is very metal-deficient, it is very bright in the mid-IR, implying an important mass of dust. It is thus mandatory to quantify the amount of dust present and to relate it to the metallicity. This can only be done by reproducing the mid-IR SED of SBS0335–052 with the help of a radiation transfer model in spherical geometry. Understanding the dust on local low-metallicity starbursting galaxies is a major step in deriving the extinction correction one should use for galaxies at high-redshift, where the amount of metals is expected to be low.
