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…

CEERS: Forging the First Dust Grains in the Universe? A Population of Galaxies with spectroscopically-derived Extremely Low Dust Attenuation (GELDA) at 4.0<z<11.4
Denis Burgarella, Véronique Buat, Patrice Theulé +35
We investigate the coevolution of metals and dust in 173 galaxies at using NIRSpec spectroscopy. Focusing on galaxies with extremely low dust attenuation, we explore t…

CEERS: Forging the First Dust -- Transition from Stellar to ISM Grain Growth in the Early Universe
Denis Burgarella, Véronique Buat, Patrice Theulé +36
We investigate the coevolution of metals and dust for 173 galaxies at 4.0<z<11.4 observed with JWST/NIRSpec. We use the code CIGALE that integrates photometric and spectroscopic da…
