Spatial correlations of extended cosmological structures

Autor: Santucho, M. V., Luparello, H. E., Lares, M., Lambas, D. G., Ruiz, A. N., Sgró, M. A.

Studies of large-scale structures in the Universe, such as superstructures or cosmic voids, have been widely used to characterize the properties of the cosmic web through statistical analyses. On the other hand, the 2-point correlation function of la

Brightest group galaxies and the large-scale environment

Autor: Luparello, H. E., Lares, M., Paz, D., Yaryura, C. Y., Lambas, D. G., Padilla, N.

We study the dependence of the properties of group galaxies on the surrounding large-scale environment, using SDSS-DR7 data. Galaxies are ranked according to their luminosity within each group and classified morphologically by the S\'ersic index. We

Clues on void evolution III: Structure and dynamics in void shells

Autor: Ruiz, A. N., Paz, D. J., Lares, M., Luparello, H. E., Ceccarelli, L., Lambas, D. G.

Publikováno v: MNRAS, 448, 1471 (2015)

Inspired on the well known dynamical dichotomy predicted in voids, where some underdense regions expand whereas others collapse due to overdense surrounding regions, we explored the interplay between the void inner dynamics and its large scale enviro

Effects of superstructure environment on galaxy groups

Autor: Luparello, H. E., Lares, M., Yaryura, C. Y., Paz, D., Padilla, N., Lambas, D. G.

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 reside in superstructures. Th
