Stellar Morphology of Optically Dark or Faint Galaxies at with JWST
Arpita Ganguly, Mengyuan Xiao, Pascal A. Oesch +11
JWST offers an unprecedented view of optically dark or faint galaxies (OFGs), previously missed by HST. They are likely massive, heavily dust-obscured star-forming galaxies (SFGs)…
What Builds and Quenches the Most Massive Galaxies in the Early Universe?
Mengyuan Xiao, Longji Bing, Guilaine Lagache +4
The first few billion years of cosmic history witnessed the rapid emergence of the most massive galaxies, yet their true space density, baryon assembly pathways, and early quenchin…
ECOGAL I. Project design and the first catalogue
Minju M. Lee, Georgios Magdis, Gabriel Brammer +10
We present ECOology for Galaxies using ALMA archive and Legacy surveys (ECOGAL), an ALMA data mining project. Using the footprints of the James Webb Space Telescope (JWST) and the…
An almost NIRCam-dark dusty star-forming galaxy at z=6.63
Longji Bing, Seb Oliver, Mengyuan Xiao +28
We present AC-2168, an almost NIRCam-dark, millimetre-bright galaxy in the COSMOS field. The source was identified blindly in ALMA Band-4 continuum data and remains undetected in t…
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,…
Noema formIng Cluster survEy (NICE): A Census of Star Formation and Cold Gas Properties in Massive protoclusters at 1.5<z<4
Luwenjia Zhou, Tao Wang, Emanuele Daddi +36
Massive protoclusters at z~1.5-4, the peak of the cosmic star formation history, are key to understanding the formation mechanisms of massive galaxies in today's clusters. However,…
