CALIFA has recently published the most significant evidence of the inside-out mass assanbly in galaxies, by the analysis of the spatially resolved starformation history of galaxies (Perez et al., 2013, ApJ Letters) .

The spatially resolved distribution of masses, at the current cosmological time, for the analyzed galaxies is shown in the following figure.

The time evolution of the stellar mass build-up can be clearly visualize in the Masss Assambly reconstruction diagram.

More results soon!
