WST -- Wide-field Spectroscopic Telescope: The Next Leap in Wide-field Spectroscopy
Roland Bacon, Olga Bellido, Philippe Dierickx +52
The Wide-field Spectroscopic Telescope (WST) is a concept for a dedicated 12-m spectroscopic survey facility designed to address some of the most important questions in astrophysic…
Embedding Equity, Diversity, and Inclusion in the WST Collaboration
Laurane Fréour, Anna Puglisi, Maria Cristina Fortuna +11
The proposed Wide-field Spectroscopic Telescope (WST) is a next-generation telescope facility with a 12-meter primary mirror that may be operational in the 2040s. The project has a…
KiDS-1000: Weak lensing and intrinsic alignment around luminous red galaxies
Maria Cristina Fortuna, Andrej Dvornik, Henk Hoekstra +8
We study the properties of luminous red galaxies (LRGs) selected from the fourth data release of the Kilo Degree Survey (KiDS-1000) via galaxy-galaxy lensing of the background gala…
Dynamical cluster masses from photometric surveys
Omar Contigiani, Henk Hoekstra, Margot M. Brouwer +5
The masses of galaxy clusters can be measured using data obtained exclusively from wide photometric surveys in one of two ways: directly from the amplitude of the weak lensing sign…
Forecasting the potential of weak lensing magnification to enhance LSST large-scale structure analyses
Constance Mahony, Maria Cristina Fortuna, Benjamin Joachimi +4
Recent works have shown that weak lensing magnification must be included in upcoming large-scale structure analyses, such as for the Vera C. Rubin Observatory Legacy Survey of Spac…
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…
Clustering of red-sequence galaxies in the fourth data release ofthe Kilo-Degree Survey
Mohammadjavad Vakili, Henk Hoekstra, Maciej Bilicki +13
We present a sample of luminous red-sequence galaxies to study the large-scale structure in the fourth data release of the Kilo-Degree Survey. The selected galaxies are defined by…
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…
