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…
Study of the relationship between the gamma ray bursts and their host galaxies
S. E. Nuza, P. B. Tissera, L. J. Pellizza +3
Gamma ray bursts (GRBs) belong to the most energetic events in the Universe. Recently, the extragalactic nature of these sources has been confirmed with the discovery of several ho…
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…
Fingerprints of the Hierarchical Building up of the Structure on the Mass-Metallicity Relation
Patricia B. Tissera, Maria E. De Rossi, C. Scannapieco
We study the mass-metallicity relation of galactic systems with stellar masses larger than 10^9 Mo in Lambda-CDM scenarios by using chemical hydrodynamical simulations. We find tha…
Feedback and metal enrichment in cosmological SPH simulations I. A model for chemical enrichment
C. Scannapieco, P. B. Tissera, S. D. M. White +1
We discuss a model for treating chemical enrichment by SNII and SNIa explosions in simulations of cosmological structure formation. Our model includes metal-dependent radiative coo…
Are violent events responsible of a Galaxy Morphological loop?
C. Scannapieco, A. V. Smith Castelli, P. B. Tissera
We use cosmological SPH simulations to investigate the effects of mergers and interactions on the formation of the bulge and disc components of galactic systems. We find that secul…
