JWST spectroscopy of galaxies at : Damped Ly absorbers reveal efficient star formation and hidden redshift biases

Kasper E. Heintz, Clara L. Pollock, Joris Witstok +23

Recent observations with JWST have revealed a remarkable population of surprisingly luminous galaxies at redshifts . Their abundance exceed predictions from simulations and e…

Stardust Galaxies at z>9: A Dust-Origin Transition Behind the Excess of UV-Bright Galaxies

D. Burgarella, V. Buat, A. K. Inoue +9

Recent JWST observations suggest that galaxies at z > 9 may be dominated by low-opacity SNe-produced dust before efficient ISM grain growth is established. This transition in dust…

Beyond Stage IV: Quasar and Galaxy Clustering and the Fundamental Physics of the 2040s

M. Guidi, M. Moresco, H. K. Herrera-Alcantar +24

Stage IV galaxy surveys (DESI, 4MOST, MOONS, Euclid) are establishing precision constraints on cosmological parameters through baryon acoustic oscillations and redshift-space disto…

How much gas and dust is in the Lyman Break Galaxy HZ10? An ALMA Band 10 to 4 and JWST/NIRSpec study of its interstellar medium

H. S. B. Algera, R. Herrera-Camus, M. Aravena +26

A complete overview of the stellar, gas and dust contents of galaxies is key to understanding their assembly at early times. However, an estimation of molecular and atomic gas rese…

Black Hole merger rates in the first billion years in light of JWST data

P. F. V. Cáceres-Burgos, P. Dayal, P. Lira +3

Context. Recent James Webb Space Telescope (JWST) discoveries have unveiled an abundance of faint and massive Active Galactic Nuclei (AGNs) at high redshifts (z=4-9), that surpass…

REBELS-IFU: Steeply rising star formation histories and the importance of dust obscuration in massive galaxies revealed by multi-wavelength observations

R. Fisher, R. A. A. Bowler, R. K. Cochrane +15

Reliable star formation rate (SFR) measurements are essential for understanding early galaxy evolution, yet derived values rely on several assumptions. To address this problem, we…
