TL;DR: It is shown that baryon-induced features in the initial conditions of the Universe are reflected in distorted form in the low-redshift galaxy distribution, an effect that can be used to constrain the nature of dark energy with future generations of observational surveys of galaxies.

TL;DR: In this article, the authors simulate the growth of galaxies and their central supermassive black holes by implementing a suite of semi-analytic models on the output of the Millennium Run, a very large simulation of the concordance A cold dark matter cosmogony.

TL;DR: In this article, it was shown that it is possible to simultaneously reproduce both the local Tully-Fisher relation and luminosity function using semi-analytic techniques applied to the standard LCDM cosmology, thus contradicting previous studies of this issue.

TL;DR: In this article, the authors used the Millennium Simulation (MS) to study the statistics of A cold dark matter (ACDM) halo concentrations at z = 0.5 and found that the average halo concentration declines monotonically with mass, up to the most massive objects that form in a ACDM universe.

TL;DR: In this paper, the authors used the Millennium Simulation (MS) to study the statistics of LCDM halo concentrations at z = 0.5, and found that the average halo concentration declines monotonically with mass; a power-law fits well the concentration-mass relation for over 3 decades in mass, up to the most massive objects to form in a LCDM universe.
