A search for star clusters in the outskirts of the Large Magellanic Cloud: indication of clusters in the age gap
M. Gatto, V. Ripepi, M. Bellazzini +7
The YMCA (Yes, Magellanic Clouds Again) and STEP ({The SMC in Time: Evolution of a Prototype interacting late-type dwarf galaxy) projects are deep g,i photometric surveys carried o…
HST resolves stars in a tiny body falling on the dwarf galaxy DDO 68
F. Annibali, M. Bellazzini, M. Correnti +9
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…
Search For Star Cluster Age Gradients Across Spiral Arms of Three LEGUS Disk Galaxies
F. Shabani, E. K. Grebel, A. Pasquali +20
One of the main theories for explaining the formation of spiral arms in galaxies is the stationary density wave theory. This theory predicts the existence of an age gradient across…
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…
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…
Legacy ExtraGalactic UV Survey with The Hubble Space Telescope. Stellar cluster catalogues and first insights into cluster formation and evolution in NGC 628
A. Adamo, J. E. Ryon, M. Messa +53
We report the large effort which is producing comprehensive high-level young star cluster (YSC) catalogues for a significant fraction of galaxies observed with the Legacy ExtraGala…
