Dust and Molecular Gas in LSB Galaxies
Abstract
Using Monte Carlo radiative transfer techniques, we model the dust content of the edge-on low surface brightness (LSB) galaxy UGC 7321. Dust alone cannot explain the large radial disk color gradients observed in this galaxy, and we find that a significant fraction (~50%) of the dust in UGC 7321 appears to be contained in a clumped medium, indicating that at least some LSB galaxies can support a modest multi-phase ISM structure. In addition, we report one of the first direct detections of molecular gas (CO) in an LSB galaxy.
