MUFASA: Galaxy Formation Simulations With Meshless Hydrodynamics [PDF]
, 2016 We present the mufasa suite of cosmological hydrodynamic simulations, which employs the gizmo meshless finite mass (MFM) code including H_2-based star formation, nine-element chemical evolution, two-phase kinetic outflows following scalings from the ...

The dark nemesis of galaxy formation : why hot haloes trigger black hole growth and bring star formation to an end [PDF]
, 2016 Galaxies fall into two clearly distinct types: `blue-sequence' galaxies that are rapidly forming young stars, and `red-sequence' galaxies in which star formation has almost completely ceased.

Fractional yields inferred from halo and thick disk stars (Serb. Astron. J. - 187 (2013), 19) [PDF]
Serbian Astronomical Journal, 2014 Due to a wrong sign in a computer code, theoretical yield ratios have been recalculated. Related changes affect only Figs. 12-13, where theoretical yield ratios are represented as vertical bands.

The influence of Galactic wind upon the star formation histories of Local Group galaxies [PDF]
, 1997 We examine the possibility that ram pressure exerted by the galactic wind from the Galaxy could have stripped gas from the Local Group dwarf galaxies, thereby affecting their star formation histories.

O and Fe abundance correlations and distributions inferred for the thick and thin disk [PDF]
Serbian Astronomical Journal, 2015 A linear [Fe/H]-[O/H] relation is found for different stellar populations in the Galaxy (halo, thick disk, thin disk) from a data sample obtained in a recent investigation (Ramґırez et al. 2013).

Physical Models of Galaxy Formation in a Cosmological Framework [PDF]
, 2014 Modeling galaxy formation in a cosmological context presents one of the greatest challenges in astrophysics today due to the vast range of scales and numerous physical processes involved.

Galaxy peculiar velocities and evolution-bias [PDF]
, 2007 Galaxy bias can be split into two components: a formation-bias based on the locations of galaxy creation, and an evolution-bias that details their subsequent evolution. In this letter we consider evolution-bias in the peaks model.

Nuclear Physics B, 1985 Abstract The present theories of galaxy formation are reviewed. The relation between peculiar velocities and the correlation function of galaxies points to the possibility that galaxies do not form uniformly everywhere. Scale invariant properties of the cluster-cluster correlations are discussed. Comparing the correlation functions in a dimensionless

Merger rates in hierarchical models of galaxy formation – II. Comparison with N-body simulations [PDF]
, 1994 We have made a detailed comparison of the results of N-body simulations with the analytical description of the merging histories of dark matter haloes presented in Lacey & Cole, which is based on an extension of the Press-Schechter method.
