Cutouts of 5 × 5 kpc² size centered on three SERRA galaxies. From left to right: Lantana (serra02:55:3350, z ≈ 7.0), Adenia (serra05:67:4486, z ≈ 6.3), and Malva (serra11:94:9149, z ≈ 4.1). From top to bottom: Gas surface density, [CII] surface brightness, and the spatially resolved conversion factor, W_[CII], in units of [(M_⊙ kpc⁻²)/(L_⊙ kpc⁻²)]. To guide the eye, dashed green, orange, and light blue lines in the Σ_[CII] maps highlight Σ_[CII] = 10^5.5, 10^6.5, and 10^7.5 L_⊙ kpc⁻², respectively.
