From dwarf spheroidals to cDs: Simulating the galaxy population in a LCDM cosmology
Qi Guo, Simon White, Michael Boylan-Kolchin +6
We apply updated semi-analytic galaxy formation models simultaneously to the stored halo/subhalo merger trees of the Millennium and Millennium-II simulations. These differ by a fac…
The Atomic to Molecular Transition and its Relation to the Scaling Properties of Galaxy Disks in the Local Universe
Jian Fu, Qi Guo, Guinevere Kauffmann +1
We extend existing semi-analytic models of galaxy formation to track atomic and molecular gas in disk galaxies. Simple recipes for processes such as cooling, star formation, supern…
Semi-Analytic Models on the Molecular and Neutral Gas in Galaxies
Jian Fu, Qi Guo, Guinevere Kauffmann
We introduced a semi-analytic model to study the detail of radial related processes on galaxy disks. Based on this recipe, we can calculate neutral and molecular gas in interstella…
What is the (Dark) Matter with Dwarf Galaxies?
Till Sawala, Qi Guo, Cecilia Scannapieco +2
We present cosmological hydrodynamical simulations of the formation of dwarf galaxies in a representative sample of haloes extracted from the Millennium-II Simulation. Our six halo…
