Galaxy Morphological Segregation in Clusters: Local vs. Global Conditions
Mariano Dominguez, Hernan Muriel, Diego G. Lambas
We study the relative fraction of galaxy morphological types in clusters, as a function of the projected local galaxy density and different global parameters: cluster projected gas…
Chemical Evolution of the Stellar and Gaseous Components of Galaxies in Hydrodynamical Cosmological Simulations
S. A. Cora, P. B. Tissera, D. G. Lambas +1
We present preliminary results on the effects of mergers on the chemical properties of galactic objects in hierarchical clustering scenarios. We adopt a hydrodynamical chemical cod…
Do clusters contain a large population of dwarf galaxies?
Carlos A. Valotto, Ben Moore, Diego G. Lambas
We analyze systematic effects in the determination of the galaxy luminosity function in clusters using a deep mock catalogue constructed from a numerical simulation of a hierarchic…
Galaxy Formation and Chemical Evolution in Hierarchical Hydrodynamical Simulations
S. A. Cora, M. B. Mosconi, P. B. Tissera +1
We report first results of an implementation of a chemical model in a cosmological code, based on the Smoothed Particle Hydrodynamics (SPH) technique. We show that chemical SPH sim…
Chemical evolution using SPH cosmological simulations. I: implementation, tests and first results
M. B. Mosconi, P. B. Tissera, S. A. Cora +1
We develop a model to implement metal enrichment in a cosmological context based on the hydrodynamical AP3MSPH code described by Tissera, Lambas and Abadi (1997).The star formation…
Correlation Function of Galaxy Groups
Manuel E. Merchan, Marcio A. G. Maia, Diego G. Lambas
We use the Updated Zwicky Catalog of galaxies (Falco et al. 1999) to generate a catalog of groups, by means of a friend-of-friend algorithm. The correlation length of the total sam…
