Supernova outflows in galaxy formation
Cecilia Scannapieco, Patricia B. Tissera, Simon D. M. White +1
We investigate the generation of galactic outflows by supernova feedback in the context of SPH cosmological simulations. We use a modified version of the code GADGET-2 which includ…
Confronting Hierarchical Clustering Models with Observations of Galaxy Pairs
Josefa Perez, Patricia Tissera, Diego G. Lambas +2
We investigate the star formation activity in galaxy pairs in chemical hydrodynamical simulations consistent with a Lambda-CDM scenario. A statistical analysis of the effects of ga…
Triggering star formation by galaxy-galaxy interactions
Patricia B. Tissera, Diego G. Lambas, M. Sol Alonso +1
We analyzed the effects of having a close companion on the star formation activity of galaxies in 8K galaxy pair catalog selected from the 2dFGRS. We found that, statistically, gal…
Comparison between Disk-like Objects Formed in Hierarchical Hydrodynamical Simulations and Observations of Spiral Galaxies
A. Saiz, R. Dominguez-Tenreiro, P. B. Tissera +1
We analyze the structural and dynamical properties of disk-like objects formed in fully consistent cosmological simulations which include inefficient star formation. Comparison wit…
Properties of Galaxy Disks in Hierarchical Hydrodynamical Simulations: Comparison with Observational Data
A. Saiz, R. Dominguez-Tenreiro, P. B. Tissera +1
We analyze the structural and dynamical properties of disk-like objects formed in fully consistent cosmological simulations with an inefficient star formation algorithm. Comparison…
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…
