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 /…

A first [CII] view of high-z quiescent galaxies

C. D'Eugenio, E. Daddi, R. Gobat +10

We present ALMA detections (or stringent upper limits) of the [CII] 158 emission line and underlying dust continuum from five massive quenched galaxies (QGs) at 2<z<4.7. We f…

Investigating the role of mergers in galaxy assembly in the early Universe (z > 5)

A. Calabrò, A. Calabrò, L. Pentericci +21

Galaxy mergers play a crucial role in shaping the morphology, the star formation, and the mass growth of galaxies across cosmic time. While mergers have been extensively investigat…

Euclid Quick Data Release (Q1). Quenching precedes bulge formation in dense environments but follows it in the field

Euclid Collaboration, F. Gentile, E. Daddi +321

(Abridged) The bimodality between star-forming discs and quiescent spheroids requires the existence of two main processes: the galaxy quenching and the morphological transformation…

Ultra High-Redshift or Closer-by, Dust-Obscured Galaxies? Deciphering the Nature of Faint, Previously Missed F200W-Dropouts in CEERS

G. Gandolfi, G. Rodighiero, L. Bisigello +42

The James Webb Space Telescope (JWST) is revolutionizing our understanding of the Universe by unveiling faint, near-infrared dropouts previously beyond our reach, ranging from exce…

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,…
