Clumpy Disc and Bulge Formation
J. Perez, O. Valenzuela, P. Tissera +1
We present a set of hydrodynamical/Nbody controlled simulations of isolated gas rich galaxies that self-consistently include SN feedback and a detailed chemical evolution model, bo…
Chemical evolution during gas-rich galaxy interactions
Josefa Perez, Leo Michel-Dansac, Patricia Tissera
We analyse a set of galaxy interactions performed by using a self-consistent chemo-hydrodynamical model which includes star formation, Supernova feedback and chemical evolution. In…
Global environmental effects versus galaxy interactions
Josefa Perez, Patricia Tissera, Nelson Padilla +3
We explore properties of close galaxy pairs and merging systems selected from the SDSS-DR4 in different environments with the aim to assess the relative importance of the role of i…
Building a control sample for galaxy pairs
Josefa Perez, Patricia Tissera, Jeremy Blaizot +1
Several observational works have attempted to isolate the effects of galaxy interactions by comparing galaxies in pairs with isolated galaxies. However, different authors have prop…
The influence of halo assembly on galaxies and galaxy groups
Tatiana Zapata, Josefa Perez, Nelson Padilla +1
In this paper, we study the variations of group galaxy properties according to the assembly history in SDSS-DR6 selected groups. Using mock SDSS group catalogues, we find two suita…
The role of tidal interactions in driving galaxy evolution
Josefa Perez, Patricia B. Tissera, Diego G. Lambas +1
We carry out a statistical analysis of galaxy pairs selected from chemical hydrodynamical simulations with the aim at assessing the capability of hierarchical scenarios to reproduc…
