Measuring σ₈ with Cluster Lensing: Biases from Unrelaxed Clusters. (2003)
Journal Article
Smith, G. P., Edge, A. C., Eke, V. R., Nichol, R. C., Smail, I., & Kneib, J. (2003). Measuring σ₈ with Cluster Lensing: Biases from Unrelaxed Clusters. Astrophysical Journal, 590(2), L79-L82. https://doi.org/10.1086/376747

We use gravitational lens models and X-ray spectral analysis of 10 X-ray-luminous galaxy clusters at z sime 0.2 to study the impact of cluster substructure on attempts to normalize the matter power spectrum. We estimate that unrelaxed clusters are 30... Read More about Measuring σ₈ with Cluster Lensing: Biases from Unrelaxed Clusters..

A median redshift of 2.4 for galaxies bright at submillimetre wavelengths (2003)
Journal Article
Chapman, S., Blain, A., Ivison, R., & Smail, I. (2003). A median redshift of 2.4 for galaxies bright at submillimetre wavelengths. Nature, 422(6933), 695-698. https://doi.org/10.1038/nature01540

A significant fraction of the energy emitted in the early Universe came from very luminous galaxies that are largely hidden at optical wavelengths (because of interstellar dust grains); this energy now forms part of the cosmic background radiation at...
