F200W ( ∼ K) JWST/NIRCam image cutout displaying I Zw 18’s main body (southeast) and Component C (northwest). We divided the main body of the galaxy in four different regions, going from the two inner star-forming regions (labeled R1 and R2, respectively), a middle section (R3), and the outermost region (R4). The Component C is also labeled in the image. In the bottom-left corner is shown a physical scale corresponding to ∼5.7″ (∼500 pc).
