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…
Weak lensing analysis of galaxy pairs using CS82 data
Elizabeth J. Gonzalez, Facundo Rodriguez, Diego García Lambas +6
In this work we analyze a sample of close galaxy pairs (relative projected separation kpc and relative radial velocities km s) using a weak lensing analy…
Compact Groups analysis using weak gravitational lensing II: CFHT Stripe 82 data
Martín Chalela, Elizabeth J. Gonzalez, Martín Makler +4
In this work we present a lensing study of Compact Groups (CGs) using data obtained from the high quality Canada-France-Hawaii Telescope Stripe 82 Survey. Using stacking techniques…
Do satellite galaxies trace matter in galaxy clusters?
Chunxiang Wang, Ran Li, Liang Gao +9
The spatial distribution of satellite galaxies encodes rich information of the structure and assembly history of galaxy clusters. In this paper, we select a redMaPPer cluster sampl…
On Mass Concentrations & Magnitude Gaps of Galaxy Systems in the CS82 Survey
André Z. Vitorelli, Eduardo S. Cypriano, Martín Makler +3
Galaxy systems with large magnitude gaps - defined as the difference in magnitude between the central galaxy and the brightest satellite in the central region - have been claimed t…
