Abell 2744: Too much substructure for Lambda CDM?
J. Schwinn, M. Jauzac, C. M. Baugh +5
The massive substructures found in Abell 2744 by Jauzac et al. (2016) present a challenge to the cold dark matter paradigm due to their number and proximity to the cluster centre.…
The Extraordinary Amount of Substructure in the Hubble Frontier Fields Cluster Abell 2744
M. Jauzac, D. Eckert, J. Schwinn +21
We present a joint optical/X-ray analysis of the massive galaxy cluster Abell 2744 (z=0.308). Our strong- and weak-lensing analysis within the central region of the cluster, i.e.,…
The Dark Matter Halos of Moderate Luminosity X-ray AGN as Determined from Weak Gravitational Lensing and Host Stellar Masses
A. Leauthaud, A. J. Benson, F. Civano +9
Understanding the relationship between galaxies hosting active galactic nuclei (AGN) and the dark matter halos in which they reside is key to constraining how black-hole fueling is…
Image Analysis for Cosmology: Results from the GREAT10 Star Challenge
T. D. Kitching, B. Rowe, M. Gill +13
We present the results from the first public blind PSF reconstruction challenge, the GRavitational lEnsing Accuracy Testing 2010 (GREAT10) Star Challenge. Reconstruction of a spati…
