The sparkling Universe: Clustering of voids and void clumps

Marcelo Lares, Andrés N. Ruiz, Heliana E. Luparello +3

We analyse the clustering of cosmic voids using a numerical simulation and the main galaxy sample from the Sloan Digital Sky Survey. We take into account the classification of void…

The sparkling Universe: a scenario for cosmic void motions

Laura Ceccarelli, Andrés N. Ruiz, Marcelo Lares +4

We perform a statistical study of the global motion of cosmic voids using both a numerical simulation and observational data. We analyse their relation to large-scale mass flows an…

The sparkling Universe: the coherent motions of cosmic voids

Diego G. Lambas, Marcelo Lares, Laura Ceccarelli +4

We compute the bulk motions of cosmic voids, using a CDM numerical simulation considering the mean velocities of the dark matter inside the void itself and that of the haloes in…

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

A. N. Ruiz, D. J. Paz, M. Lares +3

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 th…

Void Dynamics

Nelson Padilla, Dante Paz, Marcelo Lares +4

Cosmic voids are becoming key players in testing the physics of our Universe. Here we concentrate on the abundances and the dynamics of voids as these are among the best candidates…

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…

Low and High Surface Brightness Galaxies at Void Walls

L. Ceccarelli, R. Herrera-Camus, D. G. Lambas +2

We study the relative fraction of low and high surface brightness galaxies (LSBGs and HSBGs) at void walls in the SDSS DR7. We focus on galaxies in equal local density environments…

Large scale anisotropies on halo infall

Laura Ceccarelli, Dante J. Paz, Nelson Padilla +1

We perform a statistical analysis of the peculiar velocity field around dark matter haloes in numerical simulations. We examine different properties of the infall of material onto…
