Effects of superstructure environment on galaxy groups
(Oxford University Press, 2013-06-21)
We analyse properties of galaxy groups and their dependence on the large-scale environment as defined by superstructures. We find that group–galaxy cross–correlations depend only on group properties regardless the groups ...
Age and Metallicity Analysis of the Small Magellanic Cloud from Star Clusters
(2013)
We present metallicities for 15 Small Magellanic Cloud (SMC) star clusters. We add to this information the ages and metallicities of 15 additional star clusters previously studied by Parisi et al. (2009) and Parisi et al. ...
Anisotropic halo model
(2013-07-21)
In the present work, we extend the classic halo model for the large-scale matter distribution including a triaxial model for the halo profiles and their alignments. In particular, we derive general expressions for the ...
On Lifetimes of Dusty Debris Disks around A-type Stars

Properties of galaxies with peculiar nuclei

The brightest group galaxies and their large-scale environment
(Asociación Argentina de Astronomía, 2015)
We use a sample of galaxy groups in SDSS data to study their brightestgalaxies (BGG), separating groups according to their large scale environment. The statistical properties of the BGG depend on the surrounding environment ...
Abundance analysis of planet-hosting and debris-disk stars
