Euclid: Disky titans -- surprisingly high star formation efficiency in two brightest group galaxies at

F. Gentile, E. Daddi, D. Elbaz +165

We present the discovery of two disky titans in the first data release of the Euclid satellite. These sources are massive () star-forming (SFR /…

Euclid Quick Data Release (Q1). LEMON -- Lens Modelling with Neural networks. Automated and fast modelling of Euclid gravitational lenses with a singular isothermal ellipsoid mass profile

Euclid Collaboration, V. Busillo, C. Tortora +312

The Euclid mission aims to survey around 14000 deg^{2} of extragalactic sky, providing around 10^{5} gravitational lens images. Modelling of gravitational lenses is fundamental to…

Star formation quenching precedes morphological transformation in COSMOS-WEB's richest galaxy groups

Z. Ghaffari, G. Gozaliasl, A. Biviano +26

We analyzed the 25 richest galaxy groups in COSMOS-Web at z = 0.18-3.65, identified via the AMICO algorithm. These groups contain 20-30 galaxies with high (>75%) membership probabi…

Active galactic nuclei-heated dust revealed in "little red dots"

I. Delvecchio, E. Daddi, B. Magnelli +11

Little red dots (LRDs) are a puzzling population of extragalactic sources whose origin is highly debated. In this {work}, we performed a comprehensive stacking analysis of NIRCam,…

The observed total star formation rate function up to z \sim 6: complementary UV and IR contributions and comparison with state-of-the-art galaxy formation models

A. Traina, C. Gruppioni, I. Delvecchio +21

We investigate how the obscured IR-derived and the dust-corrected UV star formation rate functions (SFRFs) compare with each other, and with predictions from state-of-the-art theor…

Euclid Quick Data Release (Q1). A first view of the star-forming main sequence in the Euclid Deep Fields

Euclid Collaboration, A. Enia, L. Pozzetti +348

The star-forming main sequence (SFMS) is a tight relation observed between stellar masses and star formation rates (SFR) in a population of galaxies. This relation is observed at d…
