The Abundance and Properties of Barred Galaxies out to z ∼ 4 Using JWST CEERS Data

We present the first estimate of the observed fraction and properties of bars out to z  ∼ 4 using JWST CEERS NIRCam images. We analyze 1770 galaxies with M _⋆  > 10 ^10 M _⊙ at 0.5 ≤ z ≤ 4 and identify barred galaxies from 839 moderately inclined disk galaxies via ellipse fits and visual classifi...
