Galaxy pairs in cosmological simulations: effects of interactions on colours and chemical abundances
M. Josefa Perez, Patricia B. Tissera, Cecilia Scannapieco +3
We perform an statistical analysis of galaxies in pairs in a Lambda-CDM scenario by using the chemical GADGET-2 of Scannapieco et al. (2005) in order to study the effects of galaxy…

Galaxy Pairs in cosmological simulations: Effects of interactions on star formation
M. Josefa Perez, Patricia B. Tissera, Diego G. Lambas +1
We carried out a statistical analysis of galaxy pairs in hydrodynamical Lambda-CDM simulations. We focused on the triggering of star formation by interactions and analysed the enha…

Effects of collisions and interactions on star formation in galaxy pairs in the field
Josefa Perez, Patricia B. Tissera, Diego G. Lambas
By using cosmological simulations, we studied the effects of galaxy interactionson the star formation activity in the local Universe. We selected galaxy pairs from the 3D galaxy di…
