New metallicity profile grids generated using the GAM. Each curve illustrates the radial metallicity profile of stars formed at different epochs in the Universe’s history, ranging from 0 to t Gyr (age of the Universe). It is also worth mentioning that each subplot has its y-axis (R) truncated up to 25 kpc. Also, it is worth mentioning that the GAM does not limit the radii it can reach in a regression. Therefore, we chose to display up to physically meaningful radii.
