Journal ArticleDOI
Antilensing: the bright side of voids.
Krzysztof Bolejko,Chris Clarkson,Roy Maartens,Roy Maartens,David Bacon,Nikolai Meures,Emma Beynon +6 more
TL;DR: Contrary to the usual expectation, objects on the far side of a void are brighter than they would be otherwise, and the local dynamics of matter in and near the void is crucial and is only captured by the full relativistic lensing convergence.
Journal ArticleDOI
The XMM cluster survey: Testing chameleon gravity using the profiles of clusters
H. Wilcox,David Bacon,Robert C. Nichol,P. Rooney,Ayumu Terukina,A. Kathy Romer,Kazuya Koyama,Gong-Bo Zhao,Ross Hood,Robert G. Mann,Matt Hilton,Maria Manolopoulou,Martin Sahlén,Chris A. Collins,Andrew R. Liddle,Julian A. Mayers,Nicola Mehrtens,Christopher J. Miller,John P. Stott,Pedro T. P. Viana +19 more
TL;DR: In this article, the authors used a multiparameter Markov chain Monte Carlo analysis to constrain the two chameleon gravity parameters (beta and phi∞) on the stacked profiles of 58 clusters at higher redshifts (0.1 < z < 1.2).
Journal ArticleDOI
Computer simulation of reactions between an edge dislocation and glissile self-interstitial clusters in iron
TL;DR: In this paper, an atomic-scale computer simulation is used to investigate the reaction of self-interstitial atoms to an edge dislocation gliding in α-iron under stress for the situation where b is inclined to the dislocation slip plane.
Journal ArticleDOI
The dark matter environment of the Abell 901/902 supercluster: a weak lensing analysis of the HST STAGES survey
Catherine Heymans,Catherine Heymans,Meghan E. Gray,Chien Y. Peng,Chien Y. Peng,Ludovic Van Waerbeke,Eric F. Bell,Christian Wolf,David Bacon,Michael L. Balogh,Fabio D. Barazza,Marco Barden,Asmus Böhm,John A. R. Caldwell,Boris Häußler,Knud Jahnke,Shardha Jogee,Eelco van Kampen,Kyle Lane,Daniel H. McIntosh,Klaus Meisenheimer,Yannick Mellier,Sebastián F. Sánchez,Andy Taylor,Lutz Wisotzki,X. Z. Zheng +25 more
TL;DR: In this paper, a high-resolution dark matter reconstruction of the z = 0.165 Abell 901/902 supercluster from a weak lensing analysis of the Hubble Space Telescope STAGES survey is presented.
Journal ArticleDOI
Atomic-scale modeling of dislocations and related properties in the hexagonal-close-packed metals
David Bacon,Vaclav Vitek +1 more
TL;DR: In this article, the core structure of dislocations responsible for the primary slip modes and the nature and properties of the defects created by radiation damage in several hcp metals are discussed.
