Clues on void evolution I: Large scale galaxy distributions around voids
L. Ceccarelli, D. Paz, M. Lares +2
We perform a statistical study focused on void environments. We examine galaxy density profiles around voids in the SDSS, finding a correlation between void--centric distance to th…
Clues on void evolution II: Measuring density and velocity profiles on SDSS galaxy redshift space distortions
Dante Paz, Marcelo Lares, Laura Ceccarelli +2
Using the redshift-space distortions of void-galaxy cross-correlation function we analyse the dynamics of voids embedded in different environments. We compute the void-galaxy cross…
Anisotropic Halo Model
M. A. Sgró, D. J. Paz, M. E. Merchán
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,…
Effects of superstructure environment on galaxy groups
H. E. Luparello, M. Lares, C. Y. Yaryura +3
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 o…
