The ensemble of chemical element abundance measurements for stars, along with precision
distances and orbit properties, provides high-dimensional data to study the evolution of the …

We present a blind time-delay strong lensing (TDSL) cosmographic analysis of the doubly
imaged quasar SDSS 1206+ 4332. We combine the relative time delay between the quasar …

We study the physical properties (size, stellar mass, luminosity, and star formation rate) and
scaling relations for a sample of 166 star-forming clumps with redshift z∼ 2–6.2. They are …

We present wide-field, ground-based Johnson–Cousins UBVRI photometry for 48 Galactic
globular clusters based on about 90 000 public and proprietary images. The photometry is …

ABSTRACT Pristine_183. 6849+ 04.8619 (P1836849) is an extremely metal-poor ([Fe/H]=−
3.3±0.1) star on a prograde orbit confined to the Galactic disc. Such stars are rare and may …

ABSTRACT JWST imaging of the rich galaxy cluster Abell 2744 at z= 0.308 has been used
by the UNCOVER team to construct mosaic images in the NIRCam filters. The exceptionally …

Theoretical stellar libraries have been increasingly used to overcome limitations of empirical
libraries, eg by exploring atmospheric parameter spaces not well represented in the latter …

Supernova (SN) explosions have been sought for decades as a possible source of dust in
the Universe, providing the seeds of galaxies, stars, and planetary systems. SN 1987A offers …

Gaia EDR3 data were used to identify potential members in the outskirts of three ultra-faint
dwarf (UFD) galaxies: Coma Berenices (> 2 Rh), Ursa Major I (∼ 4 Rh), and Boötes I (∼ 4 …

To reduce and analyse astronomical images, astronomers can rely on a wide range of
libraries providing low-level implementations of legacy algorithms. However, combining …
