KiDS+2dFLenS+GAMA: Testing the cosmological model with the statistic
A. Amon, C. Blake, C. Heymans +17
We present a new measurement of , which combines measurements of weak gravitational lensing, real-space galaxy clustering and redshift space distortions. This statistic…
Maximal compression of the redshift space galaxy power spectrum and bispectrum
Davide Gualdi, Marc Manera, Benjamin Joachimi +1
We explore two methods of compressing the redshift space galaxy power spectrum and bispectrum with respect to a chosen set of cosmological parameters. Both methods involve reducing…
Weak lensing deflection of three-point correlation functions
Susan Pyne, Benjamin Joachimi, Hiranya V. Peiris
Weak gravitational lensing alters the apparent separations between observed sources, potentially affecting clustering statistics. We derive a general expression for the lensing def…
The mass dependence of dark matter halo alignments with large-scale structure
Davide Piras, Benjamin Joachimi, Björn Malte Schäfer +3
Tidal gravitational forces can modify the shape of galaxies and clusters of galaxies, thus correlating their orientation with the surrounding matter density field. We study the dep…
KiDS-i-800: Comparing weak gravitational lensing measurements in same-sky surveys
A. Amon, C. Heymans, D. Klaes +21
We present a weak gravitational lensing analysis of 815 square degree of -band imaging from the Kilo-Degree Survey (KiDS--800). In contrast to the deep -band observations,…
Morpho-z: improving photometric redshifts with galaxy morphology
John Y. H. Soo, Bruno Moraes, Benjamin Joachimi +10
We conduct a comprehensive study of the effects of incorporating galaxy morphology information in photometric redshift estimation. Using machine learning methods, we assess the cha…
