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…
Implications of JWST galaxies for galaxy formation at high redshift
Yuxiang Qin, Sreedhar Balu, J. Stuart B. Wyithe
Using a semi-analytic galaxy-formation model, we study analogues of 8 recently discovered JWST galaxies at . We select analogues from a cosmological simulation with a $…
The JWST FRESCO Survey: Legacy NIRCam/Grism Spectroscopy and Imaging in the two GOODS Fields
P. A. Oesch, G. Brammer, R. P. Naidu +38
We present the JWST Cycle 1 53.8hr medium program FRESCO, short for "First Reionization Epoch Spectroscopically Complete Observations". FRESCO covers 62 arcmin in each of the t…
Dark-ages reionization and galaxy formation simulation -- XXI. Constraining the evolution of the ionizing escape fraction
Simon J. Mutch, Bradley Greig, Yuxiang Qin +2
The fraction of ionizing photons that escape their host galaxies to ionize hydrogen in the inter-galactic medium (IGM) is a critical parameter in analyses of the reionization era.…
