KiDS-1000: Constraints on the intrinsic alignment of luminous red galaxies

Maria Cristina Fortuna, Henk Hoekstra, Harry Johnston +11

We constrain the luminosity and redshift dependence of the intrinsic alignment (IA) of a nearly volume-limited sample of luminous red galaxies selected from the fourth public data…

Strong detection of the CMB lensingxgalaxy weak lensingcross-correlation from ACT-DR4,PlanckLegacy and KiDS-1000

Naomi Clare Robertson, David Alonso, Joachim Harnois-Déraps +48

We measure the cross-correlation between galaxy weak lensing data from the Kilo Degree Survey (KiDS-1000, DR4) and cosmic microwave background (CMB) lensing data from the Atacama C…

The PAU Survey: Intrinsic alignments and clustering of narrow-band photometric galaxies

Harry Johnston, Benjamin Joachimi, Peder Norberg +20

We present the first measurements of the projected clustering and intrinsic alignments (IA) of galaxies observed by the Physics of the Accelerating Universe Survey (PAUS). With pho…

The halo model as a versatile tool to predict intrinsic alignments

Maria Cristina Fortuna, Henk Hoekstra, Benjamin Joachimi +4

Intrinsic alignments (IAs) of galaxies are an important contaminant for cosmic shear studies, but the modelling is complicated by the dependence of the signal on the source galaxy…

GAMA+KiDS: Alignment of galaxies in galaxy groups and its dependence on galaxy scale

Christos Georgiou, Nora Elisa Chisari, Maria Cristina Fortuna +11

Intrinsic galaxy alignments are a source of bias for weak lensing measurements as well as a tool for understanding galaxy formation and evolution. In this work, we measure the alig…

KiDS+GAMA: Intrinsic alignment model constraints for current and future weak lensing cosmology

Harry Johnston, Christos Georgiou, Benjamin Joachimi +8

We directly constrain the non-linear alignment (NLA) model of intrinsic galaxy alignments, analysing the most representative and complete flux-limited sample of spectroscopic galax…
