Gas and Metal Distributions within Simulated Disk Galaxies
  We highlight two research strands related to our ongoing chemodynamical
Galactic Archaeology efforts: (i) the spatio-temporal infall rate of gas onto
the disk, drawing analogies with the infall behaviour imposed by classical
galactic chemical evolution models of inside-out disk growth; (ii) the radial
age gradient predicted by spectrophometric models of disk galaxies. In relation
to (i), at low-redshift, we find that half of the infall onto the disk is gas
associated with the corona, while half can be associated with cooler gas
streams; we also find that gas enters the disk preferentially orthogonal to the
system, rather than in-plane. In relation to (ii), we recover age gradient
troughs/inflections consistent with those observed in nature, without recourse
to radial migrations.
