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 tim…

Accelerated Formation of Ultra-Massive Galaxies in the First Billion Years
Mengyuan Xiao, Pascal Oesch, David Elbaz +35
Recent JWST observations have revealed an unexpected abundance of massive galaxy candidates in the early Universe, extending further in redshift and to lower luminosity than what h…

Unveiling the hidden universe with JWST: The contribution of dust-obscured galaxies to the stellar mass function at
R. Gottumukkala, L. Barrufet, P. A. Oesch +17
With the advent of JWST, we can probe the rest-frame optical emission of galaxies at with high sensitivity and spatial resolution, making it possible to accurately characteri…
