KiDS-Legacy: Angular galaxy clustering from deep surveys with complex selection effects
Ziang Yan, Angus H. Wright, Nora Elisa Chisari +20
Photometric galaxy surveys, despite their limited resolution along the line of sight, encode rich information about the large-scale structure (LSS) of the Universe thanks to the hi…
Constraining the dispersion measure redshift relation with simulation-based inference
Koustav Konar, Robert Reischke, Steffen Hagstotz +2
We use the dispersion measure (DM) of localised Fast Radio Bursts (FRBs) to constrain cosmological and host galaxy parameters using simulation-based inference (SBI) for the first t…
KiDS-Legacy: Covariance validation and the unified OneCovariance framework for projected large-scale structure observables
Robert Reischke, Sandra Unruh, Marika Asgari +24
We introduce OneCovariance, an open-source software designed to accurately compute covariance matrices for an arbitrary set of two-point summary statistics across a variety of larg…
6x2pt: Forecasting gains from joint weak lensing and galaxy clustering analyses with spectroscopic-photometric galaxy cross-correlations
Harry Johnston, Nora Elisa Chisari, Shahab Joudaki +25
We explore the enhanced self-calibration of photometric galaxy redshift distributions, , through the combination of up to six two-point functions. Our config…
Enhancing Photometric Redshift Catalogs Through Color-Space Analysis: Application to KiDS-Bright Galaxies
Priyanka Jalan, Maciej Bilicki, Wojciech A. Hellwing +11
We present a method to refine photometric redshift galaxy catalogs by comparing their color-space matching with overlapping spectroscopic calibration data. We focus on cases where…
Fast radio bursts as a probe of gravity on cosmological scales
Dennis Neumann, Robert Reischke, Steffen Hagstotz +1
We explore the potential for improving constraints on gravity by leveraging correlations in the dispersion measure derived from Fast Radio Bursts (FRBs) in combination with cosmic…
KiDS-1000 and DES-Y1 combined: Cosmology from peak count statistics
Joachim Harnois-Deraps, Sven Heydenreich, Benjamin Giblin +10
We analyse the fourth data release of the Kilo Degree Survey (KiDS-1000) and extract cosmological parameter constraints based on the cosmic shear peak count statistics. Peaks are i…
