Connecting Young Star Clusters to CO Molecular Gas in NGC 7793 with ALMA-LEGUS
K. Grasha, D. Calzetti, L. Bittle +20
We present an investigation of the relationship between giant molecular cloud (GMC) properties and the associated stellar clusters in the nearby flocculent galaxy NGC 7793. We comb…
The Missing Satellites of the Magellanic Clouds? Gaia Proper Motions of the Recently Discovered Ultra-Faint Galaxies
Nitya Kallivayalil, Laura Sales, Paul Zivick +7
According to LCDM theory, hierarchical evolution occurs on all mass scales, implying that satellites of the Milky Way should also have companions. The recent discovery of ultra-fai…
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…
Star Formation Histories of the LEGUS Dwarf Galaxies (I): recent History of NGC1705, NGC4449 and Holmberg II
M. Cignoni, E. Sacchi, A. Aloisi +19
We use HST observations from the Legacy Extragalactic UV Survey to reconstruct the recent star formation histories (SFHs) of three actively star-forming dwarf galaxies, NGC4449, Ho…
A study of two dwarf irregular galaxies with asymmetrical star formation distributions
Deidre A. Hunter, Samavarti Gallardo, Hong-Xin Zhang +23
Two dwarf irregular galaxies DDO 187 and NGC 3738 exhibit a striking pattern of star formation: intense star formation is taking place in a large region occupying roughly half of t…
