We present new Hubble Space Telescope (HST) imaging of a stream-like system associated with the dwarf galaxy DDO 68, located in the Lynx-Cancer Void at a distance of D12.65 M…
Star Formation Histories of the LEGUS dwarf galaxies. II. Spatially resolved star formation history of the Magellanic irregular NGC 4449
Elena Sacchi, Michele Cignoni, Alessandra Aloisi +16
We present a detailed study of the Magellanic irregular galaxy NGC 4449 based on both archival and new photometric data from the Legacy Extragalactic UV Survey, obtained with the H…
Extinction Maps and Dust-to-Gas Ratios in Nearby Galaxies with LEGUS
L. Kahre, R. A. Walterbos, H. Kim +44
We present a study of the dust-to-gas ratios in five nearby galaxies NGC 628 (M74), NGC 6503, NGC 7793, UGC 5139 (Holmberg I), and UGC 4305 (Holmberg II). Using Hubble Space Telesc…
The Very Massive Star Content of the Nuclear Star Clusters in NGC 5253
