Core Cosmology Library: Precision Cosmological Predictions for LSST
Nora Elisa Chisari, David Alonso, Elisabeth Krause +27
The Core Cosmology Library (CCL) provides routines to compute basic cosmological observables to a high degree of accuracy, which have been verified with an extensive suite of valid…
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…
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…
Quantifying baryon effects on the matter power spectrum and the weak lensing shear correlation
Aurel Schneider, Romain Teyssier, Joachim Stadel +4
Feedback processes from baryons are expected to strongly affect weak-lensing observables of current and future cosmological surveys. In this paper we present a new parametrisation…
Galaxy orientation with the cosmic web across cosmic time
S. Codis, A. Jindal, N. E. Chisari +4
This work investigates the alignment of galactic spins with the cosmic web across cosmic time using the cosmological hydrodynamical simulation Horizon-AGN. The cosmic web structure…
The dependence of intrinsic alignment of galaxies on wavelength using KiDS and GAMA
Christos Georgiou, Harry Johnston, Henk Hoekstra +6
The outer regions of galaxies are more susceptible to the tidal interactions that lead to intrinsic alignments of galaxies. The resulting alignment signal may therefore depend on t…
