The Large Magellanic Cloud through the lens of the James Webb Space Telescope: Binaries and the mass function in the galaxy's outskirts
M. V. Legnardi, F. Muratore, A. P. Milone +16
Nearby galaxies such as the Large Magellanic Cloud (LMC) offer an ideal laboratory to test the initial mass function under different physical conditions, but previous works have be…
Rubin Data Preview 1: Extending the View of Unresolved Binary Stars in 47 Tucanae
Giacomo Cordoni, Luca Casagrande, Helmut Jerjen
Until now, the study of unresolved main sequence binary stars in globular clusters has been possible almost exclusively in their central regions with deep Hubble Space Telescope (H…
The coherent satellite velocity field around the interacting spiral galaxy pair NGC5713/19: signature of two galaxy groups merging
Helmut Jerjen, Simon Deeley, Holger Baumgardt +1
The luminous spirals NGC5713 and NGC5719 form an interacting galaxy pair 94 kpc apart and are connected by a straight, elongated neutral hydrogen structure extending over 200 kpc.…
New dwarf galaxy candidates in the M106, NGC3521, and UGCA127 groups with the Hyper Suprime Camera
Oliver Müller, Helmut Jerjen, Salvatore Taibi +3
The local universe is still full of hidden dwarf galaxies to be discovered using deep imaging campaigns. Here we present the third paper in a series to search for low-surface brigh…
IFUM Integrated Field Spectroscopy of Ten M104 Satellite Galaxy Candidates
Ethan Crosby, Mario Mateo, Ivanna Escala +3
We report the spectroscopic analysis of ten satellite galaxy candidates in the sphere of influence of the Sombrero galaxy (M104, NGC4594), based on data obtained with IFUM (Integra…
