Quiescent fractions in high-redshift galaxy groups reflect their hot-or-cold state of gas accretion
Guillaume Elias, Emanuele Daddi, Chiara D'Eugenio +15
Cold accretion and quenching are closely related aspects of galaxy evolution, as sustained gas supply is required to maintain star formation. High-redshift galaxy groups therefore…
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…
Ly-alpha emission reveals two satellite halos around massive groups at z ~ 3: the puzzling case of a quiescent central galaxy
Sicen Guo, Emanuele Daddi, Raphael Gobat +17
We present the discovery and characterisation of two Ly nebulae (LANs), RO-1001-Sat and RO-0959-Sat, as satellite structures of two giant LANs at and 3.092. They are f…
Cosmic Vine: High abundance of massive galaxies and dark matter halos in a forming cluster at z=3.44
Nikolaj B. Sillassen, Shuowen Jin, Georgios E. Magdis +10
The Cosmic Vine is a massive protocluster at z=3.44 in the JWST CEERS field, offering an ideal laboratory for studying the early phases of cluster formation. Using the data from th…
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,…
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…
Revealing the hidden cosmic feast: A z=4.3 galaxy group hosting two optically dark, efficiently star-forming galaxies
Malte Brinch, Shuowen Jin, Raphael Gobat +11
We present the confirmation of a compact galaxy group candidate, CGG-z4, at in the COSMOS field. This structure was identified by two spectroscopically confirmed $K…
Behind the dust veil: A panchromatic view of an optically dark galaxy at z=4.82
Nikolaj B. Sillassen, Shuowen Jin, Georgios E. Magdis +30
Optically dark dusty star-forming galaxies (DSFGs) play an essential role in massive galaxy formation at early cosmic time, however their nature remains elusive. Here we present a…
NOEMA formIng Cluster survEy (NICE): Characterizing eight massive galaxy groups at in the COSMOS field
Nikolaj B. Sillassen, Shuowen Jin, Georgios E. Magdis +41
The NOEMA formIng Cluster survEy (NICE) is a large program targeting 69 massive galaxy group candidates at in six deep fields. We report spectroscopic confirmation of eight g…
A photo-z cautionary tale: Redshift confirmation of COSBO-7 at z=2.625
Shuowen Jin, Nikolaj B. Sillassen, Jacqueline Hodge +21
Photometric redshifts are widely used in studies of dusty star-forming galaxies (DSFGs), but catastrophic photo- failure can undermine all redshift-dependent results. Here we re…
DEIMOS spectroscopy of protocluster candidate in COSMOS -- A massive protocluster embedded in a large scale structure?
Malte Brinch, Thomas R. Greve, David B. Sanders +14
We present the results of our Keck/DEIMOS spectroscopic follow-up of candidate galaxies of i-band-dropout protocluster candidate galaxies at in the COSMOS field. We secure…
Cosmic Vine: A z=3.44 large-scale structure hosting massive quiescent galaxies
Shuowen Jin, Nikolaj B. Sillassen, Georgios E. Magdis +15
We report the discovery of a large-scale structure at z=3.44 revealed by JWST data in the Extended Groth Strip (EGS) field. This structure, called the Cosmic Vine, consists of 20 g…
Uncovering the MIR emission of quiescent galaxies with
David Blánquez-Sesé, G. E. Magdis, C. Gómez-Guijarro +15
We present a study of the mid-IR (MIR) emission of quiescent galaxies (QGs) beyond the local universe. Using deep imaging in the SMACS-0723 cluster field we identify a mass…
Noema formIng Cluster survEy (NICE): Discovery of a starbursting galaxy group with a radio-luminous core at z=3.95
Luwenjia Zhou, Tao Wang, Emanuele Daddi +34
The study of distant galaxy groups and clusters at the peak epoch of star formation is limited by the lack of a statistically and homogeneously selected and spectroscopically confi…
Massive galaxy formation caught in action at z~5 with JWST
