MW-like (M_stellar ∼ 5 × 10¹⁰ M_⊙) galaxies at six different cosmic epochs in our study. Each individual stamp has a 70 × 70 kpc size. Note that the background for each image appears in black and white in order to highlight the level at which the noise starts to dominate. The lowest redshift galaxy belongs to our Local Universe reference sample (Chamba et al. 2022) based on the IAC Stripe 82 Legacy Project (Trujillo & Fliri 2016), while the rest of images are HST data. These objects were selected to have representative sizes (R_edge, golden ellipses) of galaxies at those redshifts. Note how the sizes (using our in-situ star formation criterion) decrease with redshift, while the effective radii (r_e, blue ellipses) do not change appreciably.
