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…
Milky Way type galaxies in a LCDM cosmology
Maria E. De Rossi, Patricia B. Tissera, Gabriella De Lucia +1
We analyse a sample of 52,000 Milky Way (MW) type galaxies drawn from the publicly available galaxy catalogue of the Millennium Simulation with the aim of studying statistically th…
Rotation curve bifurcations as indicators of close recent galaxy encounters
S. Pedrosa, P. B. Tissera, I. Fuentes-Carrera +1
Rotation curves of interacting galaxies often show that velocities are either rising or falling in the direction of the companion galaxy. We seek to reproduce and analyse these fea…
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…
Effects of Supernova Feedback on the Formation of Galaxy Disks
Cecilia Scannapieco, Patricia B. Tissera, Simon D. M. White +1
We use cosmological simulations in order to study the effects of supernova (SN) feedback on the formation of a Milky Way-type galaxy of virial mass ~10^12 M_sun/h. We analyse a set…
The mass-metallicity relation of interacting galaxies
L. Michel-Dansac, D. G. Lambas, M. S. Alonso +1
We study the mass-metallicity relation of galaxies in pairs and in isolation taken from the SDSS-DR4 using the stellar masses and oxygen abundances derived by Tremonti et al. (2004…
