Using neural networks to estimate redshift distributions. An application to CFHTLenS
Christopher Bonnett
We present a novel way of using neural networks (NN) to estimate the redshift distribution of a galaxy sample. We are able to obtain a probability density function (PDF) for each g…
CFHTLenS: Co-evolution of galaxies and their dark matter haloes
Michael J. Hudson, Bryan R. Gillis, Jean Coupon +16
Galaxy-galaxy weak lensing is a direct probe of the mean matter distribution around galaxies. The depth and sky coverage of the CFHT Legacy Survey yield statistically significant g…
CFHTLenS: The relation between galaxy dark matter haloes and baryons from weak gravitational lensing
Malin Velander, Edo van Uitert, Henk Hoekstra +16
We present a study of the relation between dark matter halo mass and the baryonic content of host galaxies, quantified via luminosity and stellar mass. Our investigation uses 154 d…
CFHTLenS: The Environmental Dependence of Galaxy Halo Masses from Weak Lensing
Bryan R. Gillis, Michael J. Hudson, Thomas Erben +16
We use weak gravitational lensing to analyse the dark matter halos around satellite galaxies in galaxy groups in the CFHTLenS dataset. This dataset is derived from the CFHTLS-Wide…
CFHTLenS: Higher-order galaxy-mass correlations probed by galaxy-galaxy-galaxy lensing
P. Simon, T. Erben, P. Schneider +16
We present the first direct measurement of the galaxy-matter bispectrum as a function of galaxy luminosity, stellar mass, and SED type. Our analysis uses a galaxy-galaxy-galaxy len…
CFHTLenS: Combined probe cosmological model comparison using 2D weak gravitational lensing
Martin Kilbinger, Liping Fu, Catherine Heymans +20
We present cosmological constraints from 2D weak gravitational lensing by the large-scale structure in the Canada-France Hawaii Telescope Lensing Survey (CFHTLenS) which spans 154…
