Cold dust and molecular gas towards the centers of Magellanic type galaxies and irregulars. I. The data

Abstract

We present 1300 μm continuum emission measurements and observations of the 12CO (1-0) and (2-1) transition towards the centers of 64 Magellanic type galaxies (Sdm/Sm) and irregulars (Im/IO/Irr). The sources are selected to have IRAS flux densities S100 μm ≥ 1000 mJy and optical diameters mainly below 180″. We were able to detect 12CO towards 41 and the continuum emission towards 28 galaxies. In addition, we obtained the corresponding data for a set of 6 complementary galaxies of different morphological type.
