Herschel Maps of Local Group Galaxies Overview
Local Group Overview Local Group Primary Data Access


Because the galaxies of the Local Group have such large angular sizes, much of their diffuse, large-angular-scale emission is filtered out by the Herschel data reduction process. This work restores this previously missed dust in Herschel observations of the Large Magellanic Cloud, Small Magellanic Cloud, M31, and M33 by combining Herschel data (including new reductions for the Magellanic Clouds), in Fourier space, with lower-resolution data from all-sky surveys (Planck, IRAS, and COBE) that did not miss the extended emission.

If you use Local Group data, please cite both the journal article Clark et al. (2021) and the dataset Digital Object Identifier (DOI): 10.26131/IRSA545.
