Improved two-point correlation function estimates using glass-like distributions as a reference sample
Federico Dávila-Kurbán, Ariel G. Sanchez, Marcelo Lares +1
All estimators of the two-point correlation function are based on a random catalogue, a set of points with no intrinsic clustering following the selection function of a survey. Hig…
ROGER: Reconstructing Orbits of Galaxies in Extreme Regions using machine learning techniques
Martín de los Rios, Héctor Julián Martínez, Valeria Coenda +4
We present the ROGER (Reconstructing Orbits of Galaxies in Extreme Regions) code, which uses three different machine learning techniques to classify galaxies in, and around, cluste…
Associations of dwarf galaxies in a CDM Universe
C. Y. Yaryura, M. G. Abadi, S. Gottlober +6
Associations of dwarf galaxies are loose systems composed exclusively of dwarf galaxies. These systems were identified in the Local Volume for the first time more than thirty years…
Redshift-space effects in voids and their impact on cosmological tests. Part I: the void size function
Carlos M. Correa, Dante J. Paz, Ariel G. Sánchez +3
Voids are promising cosmological probes. Nevertheless, every cosmological test based on voids must necessarily employ methods to identify them in redshift space. Therefore, redshif…
Spatial correlations of extended cosmological structures
M. V. Santucho, H. E. Luparello, M. Lares +3
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 statistic…
How galaxies populate haloes in very low-density environments? An analysis of the Halo Occupation Distribution in cosmic voids
Ignacio. G. Alfaro, Facundo Rodriguez, Andrés N. Ruiz +1
Evidence shows properties of dark matter haloes may vary with large-scale environment. By studying the halo occupation distribution in cosmic voids it is possible to obtain useful…
