Effects of SN Feedback on the Dark Matter Distribution
Susana E. Pedrosa, Patricia B. Tissera, Cecilia Scannapieco
We use cosmological simulations to study the effects of supernova (SN) feedback on the dark matter distribution in galaxies. We simulate the formation of a Milky-Way type galaxy us…
AGNs and galaxy interactions
M. Sol Alonso, Diego G. Lambas, Patricia Tissera +1
We perform a statistical analysis of AGN host characteristics and nuclear activity for AGNs in pairs and without companions. Our study concerns a sample of AGNs derived from the SD…
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…
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…
Comparison between Disk-like Objects Formed in Hierarchical Hydrodynamical Simulations and Observations of Spiral Galaxies
A. Saiz, R. Dominguez-Tenreiro, P. B. Tissera +1
We analyze the structural and dynamical properties of disk-like objects formed in fully consistent cosmological simulations which include inefficient star formation. Comparison wit…
