The host galaxies of long-duration GRBs in a cosmological hierarchical scenario
S. E. Nuza, P. B. Tissera, L. J. Pellizza +3
We developed a Monte Carlo code to generate long-duration gamma ray burst (LGRB) events within cosmological hydrodynamical simulations consistent with the concordance model. As str…
Clues for the origin of the fundamental metallicity relations. I: The hierarchical building up of the structure
Maria E. De Rossi, Patricia B. Tissera, Cecilia Scannapieco
We analyse the evolutionary history of galaxies formed in a hierarchical scenario consistent with the concordance -CDM model focusing on the study of the relation between their…
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…
Interactions, Mergers and the Fundamental Mass Relations of Galaxies
Patricia B. Tissera, Analia Smith Castelli, Cecilia Scannapieco
We present a study of the effects of mergers and interactions on the mass distribution of galactic systems in hierarchical clustering scenarios using the disc-bulge structural para…
Feedback and metal enrichment in cosmological SPH simulations - II. A multiphase model with supernova energy feedback
Cecilia Scannapieco, Patricia B. Tissera, Simon D. M. White +1
We have developed a new scheme to treat a multiphase interstellar medium in smoothed particle hydrodynamics simulations of galaxy formation. This scheme can represent a co-spatial…
Analysis of the Luminosity-Stellar Mass-Metallicity Relation in cosmological simulations
Maria Emilia De Rossi, Patricia Beatriz Tissera, Cecilia Scannapieco
We study the Luminosity-Metallicity Relation and the Stellar Mass-Metallicity Relation by performing chemo-dynamical simulations in a cosmological scenario. Our results predict a t…
