No Tension: JWST Galaxies at $z > 10$ Consistent with Cosmological Simulations

Understand

Recent observations by JWST have uncovered galaxies in the very early universe via the JADES and CEERS surveys.

• These galaxies have been measured to have very high stellar masses with substantial star formation rates.
• There are concerns that these observations are in tension with the $\Lambda$CDM model of the universe, as the stellar masses of the galaxies are relatively high for their respective redshifts.
• Recent studies have compared the JWST observations with large-scale cosmological simulations.
