An analytical model for the dispersion measure of Fast Radio Burst host galaxies
Robert Reischke, Michael Kovač, Andrina Nicola +2
The dispersion measure (DM) of fast radio bursts (FRBs) is sensitive to the electron distribution in the Universe, making it a promising probe of cosmology and astrophysical proces…
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…
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…
Euclid and KiDS-1000: Quantifying the impact of source-lens clustering on cosmic shear analyses
L. Linke, S. Unruh, A. Wittje +150
The transition from current Stage-III surveys such as the Kilo-Degree Survey (KiDS) to the increased area and redshift range of Stage IV surveys such as Euclid will significantly i…
KiDS-SBI: Simulation-based inference analysis of KiDS-1000 cosmic shear
Maximilian von Wietersheim-Kramsta, Kiyam Lin, Nicolas Tessore +4
We present a simulation-based inference (SBI) cosmological analysis of cosmic shear two-point statistics from the fourth weak gravitational lensing data release of the ESO Kilo-Deg…
Galaxy dispersion measured by Fast Radio Bursts as a probe of baryonic feedback models
Alexander Theis, Steffen Hagstotz, Robert Reischke +1
Fast Radio Bursts (FRBs) are a sensitive probe of the electron distribution in both the large-scale structure and their host galaxies through the dispersion measure (DM) of the rad…
