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…

Investigating the Growth of Little Red Dot Descendants at z<4 with the JWST

Jean-Baptiste Billand, David Elbaz, Fabrizio Gentile +16

One of JWST's most remarkable discoveries is a population of compact red galaxies known as Little Red Dots (LRDs). Their existence raises many questions about their nature, origin,…

The Bigfoot: A footprint of a Coma cluster progenitor at z=3.98

Hanwen Sun, Tao Wang, Emanuele Daddi +13

Protoclusters, galaxy clusters' high redshift progenitors, hold the keys to understanding the formation and evolution of clusters and their member galaxies. However, their cosmolog…

Compact dust-obscured star-formation and the origin of the galaxy bimodality

Maxime Tarrasse, Carlos Gómez-Guijarro, David Elbaz +19

During the last decade, studies about highly attenuated and massive red star-forming galaxies (RedSFGs) at have suggested that they could constitute a crucial population…

Galaxy Zoo JWST: Up to 75% of discs are featureless at

R. J. Smethurst, B. D. Simmons, T. Géron +21

We have not yet observed the epoch at which disc galaxies emerge in the Universe. While high- measurements of large-scale features such as bars and spiral arms trace the evoluti…

PRIMER: JWST/MIRI reveals the evolution of star-forming structures in galaxies at z<2.5

Yipeng Lyu, Benjamin Magnelli, David Elbaz +9

The stellar structures of star-forming galaxies (SFGs) undergo significant size growth during their mass assembly and must pass through a compaction phase as they evolve into quies…
