Evidence of Galactic Center Expansion from Gaia DR3 Stars along the South North Axis: Implications for the JWST Early Galaxy Problem

G. S. Karapetian, L. E. Byzalov, M. A. Hovhannisyan +2

Recent observations with the James Webb Space Telescope (JWST) have revealed massive, evolved galaxies only a few hundred million years after the Big Bang, challenging standard cos…
