Query: Analysis of the Luminosity-Stellar Mass-Metallicity Relation in
  cosmological simulations   We study the Luminosity-Metallicity Relation and the Stellar Mass-Metallicity
Relation by performing chemo-dynamical simulations in a cosmological scenario.
Our results predict a tight linear correlation between oxygen chemical
abundance and luminosity for galactic systems up to z=3. The
Luminosity-Metallicity Relation evolves with redshift in such a way that
systems at a given oxygen abundance were ~3 dex brighter at z=3 compared to
local ones, in good agreement with observations. We determin also a
characteristic stellar mass M_c~10^(10.2) M_sun/h above which the Stellar
Mass-Metallicity Relation starts to flatten. We encounter that this mass arises
as a consequence of the hierarchical aggregation of structure in a LCDM
universe and segregates two galactic populations with different astophysical
properties.
