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…
Bright galaxy sample in the Kilo-Degree Survey Data Release 4: selection, photometric redshifts, and physical properties
M. Bilicki, A. Dvornik, H. Hoekstra +16
We present a bright galaxy sample with accurate and precise photometric redshifts (photo-zs), selected using photometry from the Kilo-Degree Survey (KiDS) Da…
Organised Randoms: Learning and correcting for systematic galaxy clustering patterns in KiDS using self-organising maps
Harry Johnston, Angus H. Wright, Benjamin Joachimi +10
We present a new method for the mitigation of observational systematic effects in angular galaxy clustering via corrective random galaxy catalogues. Real and synthetic galaxy data,…
GAMA+KiDS: Empirical correlations between halo mass and other galaxy properties near the knee of the stellar-to-halo mass relation
Edward N. Taylor, Michelle E. Cluver, Alan Duffy +16
We use KiDS weak lensing data to measure variations in mean halo mass as a function of several key galaxy properties (namely: stellar colour, specific star formation rate, Sersic i…
The bias of dark matter tracers: assessing the accuracy of mapping techniques
M. Pellejero-Ibañez, A. Balaguera-Antolínez, Francisco-Shu Kitaura +7
We present a comparison between approximated methods for the construction of mock catalogs based on the halo-bias mapping technique. To this end, we use as reference a high resolut…
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…
