The connection between surface brightness and satellite systems for central galaxies through Illustris TNG
Silvio Rodriguez, Yamila Yaryura, Jose A. Benavides +7
We analyse different properties of central low-surface-brightness galaxies (LSBGs) and their satellite systems using the simulation Illustris TNG-100, in order to deepen our unders…
Star Formation and Dust in the Cosmic Web
Massimiliano Parente, Cinthia Ragone-Figueroa, Pablo López +8
The large-scale environment of the cosmic web is believed to impact galaxy evolution, but there is still no consensus regarding the mechanisms. We use a semi-analytic model (SAM) g…
Muon capture on deuteron using local chiral potentials
L. Ceccarelli, A. Gnech, L. E. Marcucci +2
The muon capture reaction in the doublet hyperfine state is studied using nuclear potentials and consistent currents derived in chiral effective f…
The impact of void environment on AGN
Laura Ceccarelli, Fernanda Duplancic, Diego Garcia Lambas
We study the population of active galaxies in void environment in the SDSS. We use optical spectroscopic information to analyze characteristics of the emission lines of galaxies, a…
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…
Voids in the 2dFGRS and LCDM simulations: spatial and dynamical properties
Laura Ceccarelli, Nelson Padilla, Carlos Valotto +1
We perform a statistical study on the distribution and dynamics of voids in the 2dFGRS. Our statistics are tested and calibrated using mock 2dFGRS catalogues. We analyse the dynami…
Large-scale modulation of star formation in void walls
Laura Ceccarelli, Nelson Padilla, Diego Garcia Lambas

Spatial and Dynamical Properties of Voids in a LCDM Universe
N. D. Padilla, L. Ceccarelli, D. G. Lambas
We study statistical properties of voids in the distribution of mass, dark-matter haloes and galaxies (B_J<-16) in a LCDM numerical simulation populated with galaxies using a semi-…
