High Resolution Weak Lensing Mass-Mapping Combining Shear and Flexion
Francois Lanusse, Jean-Luc Starck, Adrienne Leonard +1
We propose a new mass-mapping algorithm, specifically designed to recover small-scale information from a combination of gravitational shear and flexion. Including flexion allows us…
The behaviour of dark matter associated with 4 bright cluster galaxies in the 10kpc core of Abell 3827
Richard Massey, Liliya Williams, Renske Smit +20
Galaxy cluster Abell 3827 hosts the stellar remnants of four almost equally bright elliptical galaxies within a core of radius 10kpc. Such corrugation of the stellar distribution i…
Weak lensing reconstructions in 2D & 3D: implications for cluster studies
Adrienne Leonard, Francois Lanusse, Jean-Luc Starck
We compare the efficiency with which 2D and 3D weak lensing mass mapping techniques are able to detect clusters of galaxies using two state-of-the-art mass reconstruction technique…
Detecting Mass Substructure in Galaxy Clusters: An Aperture Mass Statistic for Gravitational Flexion
Adrienne Leonard, Lindsay J. King, Stephen M. Wilkins
Gravitational flexion has recently been introduced as a technique by which one can map out and study substructure in clusters of galaxies. Previous analyses involving flexion have…
