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…
Binary stars as dynamical tracers in globular clusters .II. Evolution of the radial distribution of the binary star fraction
J. Bruce, E. Vesperini, E. Dalessandro +5
The distinct dynamical environments occupied by multiple stellar populations in globular clusters play a significant role in many aspects of cluster evolution, including the dynami…
Binary Stars as Dynamical Tracers in Globular Clusters .I. First Observations of Bimodal Spatial Distributions
M. Cadelano, E. Dalessandro, J. Bruce +7
We present the first homogeneous study of the radial distribution of the binary fraction across the full extent of six Galactic globular clusters (GCs) spanning a wide range of dyn…
The evolution of high-z proto-star clusters into local globular clusters
A. Della Croce, E. Vesperini, R. Pascale +4
The James Webb Space Telescope (JWST) detected numerous massive and relatively compact stellar clumps around proto-galaxies at high redshift (z>0.5). Their properties suggest that…
The Hubble Missing Globular Clusters Survey IV. Ultra-faint compact satellites of the Milky Way. The case of Koposov 2
M. Bellazzini, R. Pascale, E. Dodd +16
In the last decades a number of extremely faint and compact Galactic satellites (Ultra Faint Compact Satellites; UFCS) have been discovered by large panoramic surveys. Their nature…
Euclid: Early Release Observations -- Internal kinematics and the convective-transition gap of NGC 6397
M. Griggio, M. Libralato, R. Gerasimov +130
We present a 'multiple-pass' data-reduction tool designed for Euclid, based on software developed for the Hubble Space Telescope (HST), which improves the astrometric and photometr…
