Improving Weak Lensing Mass Map Reconstructions using Gaussian and Sparsity Priors: Application to DES SV
N. Jeffrey, F. B. Abdalla, O. Lahav +65
Mapping the underlying density field, including non-visible dark matter, using weak gravitational lensing measurements is now a standard tool in cosmology. Due to its importance to…
Dark matter dynamics in Abell 3827: new data consistent with standard Cold Dark Matter
Richard Massey, David Harvey, Jori Liesenborgs +23
We present integral field spectroscopy of galaxy cluster Abell 3827, using ALMA and VLT/MUSE. It reveals an unusual configuration of strong gravitational lensing in the cluster cor…
Cosmological constraints with weak lensing peak counts and second-order statistics in a large-field survey
Austin Peel, Chieh-An Lin, Francois Lanusse +3
Peak statistics in weak lensing maps access the non-Gaussian information contained in the large-scale distribution of matter in the Universe. They are therefore a promising complem…
The Mass Distribution of the Unusual Merging Cluster Abell 2146 from Strong Lensing
Joseph E. Coleman, Lindsay J. King, Masamune Oguri +11
Abell 2146 consists of two galaxy clusters that have recently collided close to the plane of the sky, and it is unique in showing two large shocks on $\textit{Chandra X-ray Observa…
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…
