Most spiral galaxies are characterized by a disk, where stars, gas and dust spread out in a characteristic pattern of twisted spiral arms, and a bright central area, named the bulge. When studying how galaxies form and evolve, it is crucial to differentiate between these two components. This represents a scientific challenge and previous studies have traditionally assumed that the disk brightnes
