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…

Chemical Abundances and the Hierarchical Clustering
Patricia B. Tissera, Diego G. Lambas
We studied the chemical enrichment of the interstellar medium and stellar population of the building blocks of current typical galaxies in the field, in cosmological hydrodynamics…
