A CMB lensing analysis of the extended mass distribution of clusters
Facundo Toscano, Heliana Luparello, Elizabeth Johana Gonzalez +1
The aim of this work is to study the anisotropic weak lensing signal associated with the mass distribution of massive clusters of galaxies using the Cosmic Microwave Background (CM…
Cluster halo shapes in CDM and SIDM models: Unveiling the DM particle nature using a weak lensing approach
Elizabeth Johana Gonzalez, Agustín Rodriguez-Medrano, Luis Alberto Pereyra +1
Self-interacting dark matter (SIDM) is an alternative to the standard collisionless cold dark matter model (CDM), allowing for interactions between the dark matter particles throug…
New catalogue of dark-matter halo properties identified in MICE-GC -- I. Analysis of density profile distributions
Elizabeth J. Gonzalez, Kai Hoffmann, Diego R. García Lambas +10
Constraints on dark matter halo masses from weak gravitational lensing can be improved significantly by using additional information about the morphology of their density distribut…
Halo cluster shapes: Insights from simulated galaxies and ICL with prospects for weak lensing applications
Elizabeth J. Gonzalez, Cinthia Ragone-Figueroa, Carlos J. Donzelli +3
We present a detailed study of the shapes and alignments of different galaxy cluster components using hydrodynamical simulations. We compute shape parameters from the Dark Matter (…
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…
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…
