A review on numerical simulations of galaxy formation is given. Different numerical methods to solve collisionless and gas dynamical systems are outlined and one particular simulation technique, Smoothed Particle Hydrodynamics, is discussed in some detail. After a short discussion of the most relevant physical processes which affect the dynamics of the

Galaxy pairs, as key probes for studying galaxy formation and evolution, provide a unique window for observing galaxy interactions, including the associated exchange of material and related galaxy formation activities.

Triggering Star Formation by Galaxy-Galaxy Interactions [PDF]
We analyzed the effects of having a close companion on the star formation activity of galaxies in the 8K galaxy pair catalog selected from the 2dFGRS. We found that, statistically, galaxies with rp < 25h−1 kpc and ΔV < 100km s−1 have enhanced star formation with respect to isolated galaxies with the same luminosity and redshift distribution.

Hierarchical galaxy formation [PDF]
We describe the GALFORM semi-analytic model for calculating the formation and evolution of galaxies in hierarchical models. It improves upon, and extends, the Cole et al 1994 model. The model employs a new Monte-Carlo algorithm to follow the merging evolution of dark matter halos with arbitrary mass resolution. It incorporates realistic descriptions of

Fractional yields inferred from halo and thick disk stars (Serb. Astron. J. - 187 (2013), 19) [PDF]
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.

O and Fe abundance correlations and distributions inferred for the thick and thin disk [PDF]
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).

Exploring the Mass–Metallicity Relationships with the DESI BGS and ELG Samples
The mass–metallicity relation (MZR) serves as a cornerstone for understanding the chemical evolution of galaxies by correlating the stellar mass of galaxies with their gas-phase metallicity.
