The effects of environment on the intrinsic shape of galaxies
Silvio Rodríguez, Nelson D. Padilla, Diego García Lambas
We measure the effect of the environment on the intrinsic shapes of spiral and elliptical galaxies by finding the 3D shape distribution and dust extinction that fits better the pro…
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…
Low X-ray Luminosity Galaxy Clusters. III: Weak Lensing Mass Determination at 0.18 z 0.70
Elizabeth Johana Gonzalez, Gael Foëx, José Luis Nilo Castellón +5
This is the third of a series of papers of low X-ray luminosity galaxy clusters. In this work we present the weak lensing analysis of eight clusters, based on observations obtained…
Brightest group galaxies and the large-scale environment
H. E. Luparello, M. Lares, D. Paz +3
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 withi…
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…
