The Early Maturity of High-Redshift Galaxies: Insights from sSFR, M/L and SFHs at z~7-14
P. Santini, M. Castellano, A. Calabrò +23
The James Webb Space Telescope (JWST) has revealed an unexpected excess of UV-bright galaxies at z>10, unaccounted for by extrapolations from pre-JWST observations and theoretical…
Before its time: a remarkably evolved protocluster core at z=7.88
Callum Witten, Pascal A. Oesch, William McClymont +11
Protoclusters represent the most extreme environments in the very early Universe. They form from large-scale dark matter overdensities, harbouring an overabundance of galaxies fed…
Starbursts hiding in the main sequence: a pathway toward quenching?
Florent Renaud, Katarina Kraljic, Jonathan Freundlich +10
Star-forming galaxies spend most of their lifetimes on the star-forming main sequence, which establishes a tight empirical and statistical relation between stellar mass and star-fo…
A systematic search for dormant galaxies at z~5-7 from the JWST NIRSpec archive
Alba Covelo-Paz, Corentin Meuwly, Pascal A. Oesch +6
JWST has revealed a population of ``dormant'' galaxies at that have recently halted their star formation and are characterized by weak emission lines and significant Balmer b…
Stochastic star formation activity of galaxies within the first billion years probed by JWST
C. Carvajal-Bohorquez, L. Ciesla, N. Laporte +8
In this work, we aim at characterizing the burstiness level of high-redshift galaxy SFHs and its evolution. We implement a stochastic SFH in CIGALE using PSD, to estimate the burst…
ACOSMOS: The dust content of massive quiescent galaxies and its evolution with cosmic time
Sylvia Adscheid, Benjamin Magnelli, Laure Ciesla +3
We study the dust content of massive () quiescent galaxies (QGs) at redshifts to place constraints on the evolution of their cold interstella…
