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…

JWST Reveals Bulge-dominated Star-forming Galaxies at Cosmic Noon
Chloë E. Benton, Erica J. Nelson, Tim B. Miller +10
Hubble Space Telescope imaging shows that most star-forming galaxies at cosmic noon -- the peak of cosmic star formation history -- appear disk-dominated, leaving the origin of the…
COSMOS-Web: stellar mass assembly in relation to dark matter halos across of cosmic history

We study the stellar mass function (SMF) and the co-evolution with dark matter halos via abundance matching in the largest redshift range to date in $0.53 \, {\rm deg}^2…
NGDEEP: The Star Formation and Ionization Properties of Galaxies at
Lu Shen, Casey Papovich, Jasleen Matharu +23
We use JWST/NIRISS slitless spectroscopy from the Next Generation Deep Extragalactic Exploratory Public (NGDEEP) Survey to investigate the physical condition of star-forming galaxi…
UNCOVER: 404 Error -- Models Not Found for the Triply Imaged Little Red Dot A2744-QSO1
Yilun Ma, Jenny E. Greene, David J. Setton +20
JWST has revealed an abundance of compact, red objects at dubbed "little red dots" (LRDs), whose SEDs display a faint blue UV continuum followed by a steep rise in th…
COSMOS-Web: A history of galaxy migrations over the stellar mass-star formation rate plane
R. C. Arango-Toro, O. Ilbert, L. Ciesla +39
The stellar mass-star formation rate (-) plane is a fundamental diagnostic for distinguishing galaxy populations. However, the evolutionary pathways of…
ALMA observations of super-early galaxies: attenuation-free model predictions
A. Ferrara, S. Carniani, F. di Mascia +3
The abundance and blue color of super-early (redshift ), luminous galaxies discovered by JWST can be explained if radiation-driven outflows have ejected their dust on kpc-sca…
Euclid preparation. Simulations and nonlinearities beyond CDM. 1. Numerical methods and validation
Euclid Collaboration, J. Adamek, B. Fiorini +268
To constrain models beyond CDM, the development of the Euclid analysis pipeline requires simulations that capture the nonlinear phenomenology of such models. We present an overv…
Not-so-little Red Dots: Two massive and dusty starbursts at z~5-7 pushing the limits of star formation discovered by JWST in the COSMOS-Web survey
Fabrizio Gentile, Caitlin M. Casey, Hollis B. Akins +24
We present the properties of two candidate massive () and dusty ( mag) galaxies at in the first 0.28 deg of the COSMOS-Web sur…
The eventful life of a luminous galaxy at z = 14: metal enrichment, feedback, and low gas fraction?
Stefano Carniani, Francesco D'Eugenio, Xihan Ji +25
JADES-GS-z14-0 is the most distant spectroscopically confirmed galaxy yet, at . With a UV magnitude of -20.81, it is one of the most luminous galaxies at cosmic dawn and its…
An Hα view of galaxy build-up in the first 2 Gyr: luminosity functions at z~4-6.5 from NIRCam/grism spectroscopy
Alba Covelo-Paz, Emma Giovinazzo, Pascal A. Oesch +22
The Hα nebular emission line is an optimal tracer for recent star formation in galaxies. With the advent of JWST, this line has recently become observable at z>3 for the first time…
