Satellites and central galaxies in SDSS: the influence of interactions on their properties
Valeria Mesa, Sol Alonso, Georgina Coldwell +2
We use SDSS-DR14 to construct a sample of galaxy systems consisting of a central object and two satellites. We adopt projected distance and radial velocity difference criteria and…
Brightest Cluster Galaxies: the centre can(not?) hold
Roberto De Propris, Michael J. West, Felipe Andrade-Santos +9
We explore the persistence of the alignment of brightest cluster galaxies (BCGs) with their local environment. We find that a significant fraction of BCGs do not coincide with the…
Infall of galaxies onto groups
M. V. Santucho, M. L. Ceccarelli, D. G. Lambas
Growth of the structure in the Universe manifest as accretion flows of galaxies onto groups and clusters. Thus, the present day properties of groups and their member galaxies are i…
Measuring the surface mass density ellipticity of redMaPPer galaxy clusters using weak-lensing
Elizabeth J. Gonzalez, Martin Makler, Diego Garcia Lambas +5
In this work we study the shape of the projected surface mass density distribution of galaxy clusters using weak-lensing stacking techniques. In particular, we constrain the averag…
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…
