KiDS-450 + 2dFLenS: Cosmological parameter constraints from weak gravitational lensing tomography and overlapping redshift-space galaxy clustering
Shahab Joudaki, Chris Blake, Andrew Johnson +19
We perform a combined analysis of cosmic shear tomography, galaxy-galaxy lensing tomography, and redshift-space multipole power spectra (monopole and quadrupole) using 450 deg…
The 2-degree Field Lensing Survey: photometric redshifts from a large new training sample to r<19.5
Christian Wolf, Andrew Johnson, Maciej Bilicki +13
We present a new training set for estimating empirical photometric redshifts of galaxies, which was created as part of the 2dFLenS project. This training set is located in a 700 sq…
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…
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…
The 6dF Galaxy Survey: Bulk Flows on Mpc scales
Morag I. Scrimgeour, Tamara M. Davis, Chris Blake +12
We measure the bulk flow of the local Universe using the 6dF Galaxy Survey peculiar velocity sample (6dFGSv), the largest and most homogeneous peculiar velocity sample to date. 6dF…
