GAMA. Stellar mass budget

We find that the spheroid/disc mass distributions for individual galaxy morphological types are well described by single Schechter function forms. We derive estimates of the total stellar mass densities in spheroids ({rho}_spheroid_=1.24+/-0.49x10^8^M_{sun}_Mpc^-3^h_0.7_) and discs ({rho}_disc_=1.20+/-0.45x10^8^M_{sun}_Mpc^-3^h_0.7_), which translates to approximately 50 per cent of the local stellar mass density in spheroids and 48 per cent in discs.

The remaining stellar mass is found in the dwarf 'little blue spheroid' class, which is not obviously similar in structure to either classical spheroid or disc populations. We also examine the variation of component mass ratios across galaxy mass and group halo mass regimes, finding the transition from spheroid to disc mass dominance occurs near galaxy stellar mass ~10^11^M_{sun}_ and group halo mass ~10^12.5^M_{sun}_/h.
