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…
Halo shapes constrained from a pure sample of central galaxies in KiDS-1000
Christos Georgiou, Henk Hoekstra, Konrad Kuijken +12
We present measurements of , the ratio of the aligned components of the projected halo and galaxy ellipticities, for a sample of central galaxies using weak gravitational lens…
Tightening weak lensing constraints on the ellipticity of galaxy-scale dark matter haloes
Tim Schrabback, Henk Hoekstra, Ludovic Van Waerbeke +19
Cosmological simulations predict that galaxies are embedded into triaxial dark matter haloes, which appear approximately elliptical in projection. Weak gravitational lensing allows…
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…
Luminous red galaxies in the Kilo Degree Survey: selection with broad-band photometry and weak lensing measurements
Mohammadjavad Vakili, Maciej Bilicki, Henk Hoekstra +5
We use the overlap between multiband photometry of the Kilo-Degree Survey (KiDS) and spectroscopic data based on the Sloan Digital Sky Survey (SDSS) and Galaxy And Mass Assembly (G…
