The chemical compositions of multiple stellar populations in the globular cluster NGC 2808
M. Carlos, A. F. Marino, A. P. Milone +8
Pseudo two-colour diagrams or Chromosome maps (ChM) indicate that NGC 2808 host five different stellar populations. The existing ChMs have been derived by the Hubble Space Telescop…
The impact of carbon and oxygen abundances on the metal-poor initial mass function
Piyush Sharda, Anish M. Amarsi, Kathryn Grasha +5
Star formation models predict that the metal-poor initial mass function (IMF) can be substantially different from that observed in the metal-rich Milky Way. This changeover occurs…
Two lensed star candidates at behind the galaxy cluster MACS J0647.7+7015
Ashish Kumar Meena, Adi Zitrin, Yolanda Jiménez-Teja +24
We report the discovery of two extremely magnified lensed star candidates behind the galaxy cluster MACS J0647.7+7015, in recent multi-band James Webb Space Telescope (JWST) NIRCam…
The Gaia-ESO survey: mapping the shape and evolution of the radial abundance gradients with open clusters
L. Magrini, C. Viscasillas Vazquez, L. Spina +27
The spatial distribution of elemental abundances and their time evolution are among the major constraints to disentangle the scenarios of formation and evolution of the Galaxy. We…
JWST's PEARLS: a new lens model for ACT-CL J01024915, "EL Gordo'', and the first red supergiant star at cosmological distances discovered by JWST
Jose M. Diego, Ashish K. Meena, Nathan J. Adams +27
The first JWST data on the massive colliding cluster El Gordo confirm 23 known families of multiply lensed images and identify 8 new members of these families. Based on these famil…
JWST reveals a possible galaxy merger in triply-lensed MACS0647JD
Tiger Yu-Yang Hsiao, Dan Coe, Abdurro'uf +63
MACS0647JD is a triply-lensed galaxy originally discovered with the Hubble Space Telescope. Here we report new JWST imaging, which clearly resolves MACS0647JD as ha…
A Highly Magnified Star at Redshift 6.2
Brian Welch, Dan Coe, Jose M. Diego +26
Galaxy clusters magnify background objects through strong gravitational lensing. Typical magnifications for lensed galaxies are factors of a few but can also be as high as tens or…
JWST Imaging of Earendel, the Extremely Magnified Star at Redshift
Brian Welch, Dan Coe, Erik Zackrisson +60
The gravitationally lensed star WHL0137-LS, nicknamed Earendel, was identified with a photometric redshift based on images taken with the Hubble Space Tele…
First Light And Reionisation Epoch Simulations (FLARES) VII: The Star Formation and Metal Enrichment Histories of Galaxies in the early Universe
Stephen M. Wilkins, Aswin P. Vijayan, Christopher C. Lovell +8
The star formation and metal enrichment histories of galaxies - at any epoch - constitute one of the key properties of galaxies, and their measurement is a core aim of observationa…
The Gaia-ESO survey: placing constraints on the origin of r-process elements
M. Van der Swaelmen, C. Viscasillas Vázquez, G. Cescutti +19
A renewed interest about the origin of \emph{r}-process elements has been stimulated by the multi-messenger observation of the gravitational event GW170817, with the detection of b…
RELICS: Small-scale Star Formation in Lensed Galaxies at
Brian Welch, Dan Coe, Adi Zitrin +13
Detailed observations of star forming galaxies at high redshift are critical to understand the formation and evolution of the earliest galaxies. Gravitational lensing provides an i…
Gaia DR3: Apsis III -- Non-stellar content and source classification
L. Delchambre, C. A. L. Bailer-Jones, I. Bellas-Velidis +78
Context. As part of the third Gaia data release, we present the contributions of the non-stellar and classification modules from the eighth coordination unit (CU8) of the Data Proc…
Gaia Data Release 3: Astrophysical parameters inference system (Apsis) I -- methods and content overview
O. L. Creevey, R. Sordo, F. Pailler +86
Gaia Data Release 3 contains a wealth of new data products for the community. Astrophysical parameters are a major component of this release. They were produced by the Astrophysica…
Gaia Data Release 3: Analysis of RVS spectra using the General Stellar Parametriser from spectroscopy
A. Recio-Blanco, P. de Laverny, P. A. Palicio +77
The chemo-physical parametrisation of stellar spectra is essential for understanding the nature and evolution of stars and of Galactic stellar populations. Gaia DR3 contains the pa…
The Gaia-ESO Public Spectroscopic Survey: Implementation, data products, open cluster survey, science, and legacy
S. Randich, G. Gilmore, L. Magrini +161
In the last 15 years different ground-based spectroscopic surveys have been started (and completed) with the general aim of delivering stellar parameters and elemental abundances f…
Finding lensed direct-collapse black holes and supermassive primordial stars
Anton Vikaeus, Daniel J Whalen, Erik Zackrisson
Direct-collapse black holes (DCBHs) may be the seeds of the first quasars, over 200 of which have now been detected at . The James Webb Space Telescope (JWST) could detect…
Possible Systematic Rotation in the Mature Stellar Population of a Galaxy
Tsuyoshi Tokuoka, Akio K. Inoue, Takuya Hashimoto +13
We present new observations with the Atacama Large Millimeter/submillimeter Array for a gravitationally-lensed galaxy at , MACS1149-JD1. [O III] 88-m emission is detected…
The Gaia-ESO Survey: Age-chemical-clock relations spatially resolved in the Galactic disc
C. Viscasillas Vázquez, L. Magrini, G. Casali +33
The last decade has seen a revolution in our knowledge of the Galaxy thanks to the Gaia and asteroseismic space missions and the ground-based spectroscopic surveys. To complete thi…
Project Hephaistos I. Upper limits on partial Dyson spheres in the Milky Way
Matías Suazo, Erik Zackrisson, Jason T. Wright +2
Dyson spheres are hypothetical megastructures built by advanced extraterrestrial civilizations to harvest radiation energy from stars. Here, we combine optical data from Gaia DR2 w…
