Searching for strong lensing by late-type galaxies in UNIONS

J. A. Acevedo Barroso, B. Clément, F. Courbin +8

Recent wide-field galaxy surveys have led to an explosion in the number of galaxy-scale strong gravitational lens candidates. However, the vast majority of them feature massive lum…

Spatial variability of CH4 and C2H2 absorptions in Jupiter's auroral regions from Juno-UVS observations

J. Vinesse, B. Bonfond, B. Benmahi +8

Color ratios derived from molecular hydrogen emissions provide valuable diagnostics for the energy of precipitating electrons and the structure of the auroral atmosphere. We aim to…

Euclid preparation. LXVIII. Extracting physical parameters from galaxies with machine learning

Euclid Collaboration, I. Kovačić, M. Baes +287

The Euclid mission is generating a vast amount of imaging data in four broadband filters at high angular resolution. This will allow the detailed study of mass, metallicity, and st…

Euclid preparation. 3-dimensional galaxy clustering in configuration space. Part I. 2-point correlation function estimation

Euclid Collaboration, S. de la Torre, F. Marulli +297

The 2-point correlation function of the galaxy spatial distribution is a major cosmological observable that enables constraints on the dynamics and geometry of the Universe. The Eu…

JWST 1.5 μm and 4.8 μm Photometry of Y Dwarfs

Loïc Albert, Sandy K. Leggett, Per Calissendorff +20

Brown dwarfs lack nuclear fusion and cool with time; the coldest known have an effective temperature below 500 K, and are known as Y dwarfs. We present a James Webb Space Telescope…
