On the weak lensing masses of a new sample of galaxy groups
Elizabeth J. Gonzalez, Facundo Rodriguez, Manuel Merchán +6
Galaxy group masses are important to relate these systems with the dark matter halo hosts. However, deriving accurate mass estimates is particularly challenging for low-mass galaxy…
Deviations from tidal torque theory: evolution of the halo spin-filament alignment
Pablo López, Marius Cautun, Dante Paz +2
The alignment between halo spins and the cosmic web is still poorly understood despite being a widely studied topic. Here, we study this alignment within the context of tidal torqu…
The galaxy size - halo mass scaling relations and clustering properties of central and satellite galaxies
Facundo Rodriguez, Antonio D. Montero-Dorta, Raul E. Angulo +2
In this work, we combine size and stellar mass measurements from the Sloan Digital Sky Server (SDSS) with the group finder algorithm of Rodriguez \& Merchán in order to determine t…
Combining FOF and halo-based algorithms for the identification of galaxy groups
Facundo Rodriguez, Manuel Merchán
Galaxy groups provide the means for a great diversity of studies that contribute to a better understanding of the structure of the universe on a large scale and allow the propertie…
GriSPy: A Python package for Fixed-Radius Nearest Neighbors Search
Martin Chalela, Emanuel Sillero, Luis Pereyra +4
We present a new regular grid search algorithm for quick fixed-radius nearest-neighbor lookup developed in Python. This module indexes a set of k-dimensional points in a regular gr…
Detection and analysis of cluster-cluster filaments
Luis A. Pereyra, Mario A. Sgró, Manuel E. Merchán +2
In this work, we identify and analyse the properties of cluster-cluster filaments within a cosmological simulation assuming that they are structures connecting maxima of the densit…
