2dFLenS and KiDS: Determining source redshift distributions with cross-correlations
Andrew Johnson, Chris Blake, Alexandra Amon +16
We develop a statistical estimator to infer the redshift probability distribution of a photometric sample of galaxies from its angular cross-correlation in redshift bins with an ov…
Cosmological neutrino simulations at extreme scale
J. D. Emberson, Hao-Ran Yu, Derek Inman +8
Constraining neutrino mass remains an elusive challenge in modern physics. Precision measurements are expected from several upcoming cosmological probes of large-scale structure. A…
The 2-degree Field Lensing Survey: design and clustering measurements
Chris Blake, Alexandra Amon, Michael Childress +16
We present the 2-degree Field Lensing Survey (2dFLenS), a new galaxy redshift survey performed at the Anglo-Australian Telescope. 2dFLenS is the first wide-area spectroscopic surve…
CFHTLenS revisited: assessing concordance with Planck including astrophysical systematics
Shahab Joudaki, Chris Blake, Catherine Heymans +9
We investigate the impact of astrophysical systematics on cosmic shear cosmological parameter constraints from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS), and the…
Revisiting CFHTLenS cosmic shear: Optimal E/B mode decomposition using COSEBIs and compressed COSEBIs
Marika Asgari, Catherine Heymans, Chris Blake +3
We present a re-analysis of the CFHTLenS weak gravitational lensing survey using Complete Orthogonal Sets of E/B-mode Integrals, known as COSEBIs. COSEBIs provide a complete set of…
