Understanding how bulges grow in galaxies is critical step towards unveiling the link between galaxy morphology and star-formation. To do so, it is necessary to decompose large sample of galaxies at different epochs into their main…
Structural decomposition of galaxies into bulge, disk, and bar components is important to address a number of scientific problems. Measuring bulge, disk, and bar structural parameters will set constraints on the violent and secular…

We have estimated the bulge-to-total ($B/T$) light ratios in the $K_s$-band for a sample of 24 S0, S0/a and Sa galaxies by applying a 2-dimensional multicomponent decomposition method. For the disk an exponential function is used, the…
