JWST observations of 47 Tucanae: I. The low-mass main sequence down to the hydrogen-burning limit

M. Scalco, R. Gerasimov, L. R. Bedin +4

We present the first results of a series of studies based on JWST observations of the globular cluster 47 Tucanae (47 Tuc, or NGC 104) obtained with NIRCam. By combining new data w…

Euclid: The convective-transition gap of 47 Tuc

M. Libralato, M. Griggio, R. Gerasimov +140

We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…

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…

JWST imaging of omega Centauri: II. Evidence for a split white dwarf cooling sequence in the near-infrared

M. Scalco, M. Salaris, L. R. Bedin +11

We present a detailed analysis of the white dwarf cooling sequence (WD CS) in omega Centauri based on combined Hubble Space Telescope (HST) and JWST observations. Our analysis conf…

JWST imaging of omega Centauri -- I. Luminosity and mass functions of its main sequence populations

M. Scalco, R. Gerasimov, L. R. Bedin +10

This paper presents the first study of the most massive globular cluster (GC) in the Milky Way, omega Centauri, employing recently acquired JWST deep images. By combining these dat…

JWST Imaging of the Closest Globular Clusters -- VI. The Lowest-Mass Objects in M 4 and the Galactic Bulge

L. R. Bedin, R. Gerasimov, A. Calamida +8

We present `James Webb Space Telescope' observations of M4 -- the closest globular cluster -- that probe the lower Main Sequence down to the hydrogen-burning limit. The unveiled st…
