KiDS-DR5: Exploring dust transport in dark matter halos of galaxies
Eray Genc, Angus H. Wright, Hendrik Hildebrandt +12
We analyse a well-defined sample of galaxies from the final data release of the Kilo-Degree Survey (KiDS-DR5), selected using magnitude, photometric redshift, and stellar mass cuts…
Baryonification IV: Constraining baryonic feedback with X-ray gas fractions
Jozef Bucko, Andrina Nicola, Aurel Schneider +8
Baryonic feedback redistributes gas around dark matter halos, suppressing the matter power spectrum at scales now probed by weak lensing surveys. X-ray observations directly trace…
Analytical covariances for catalogue-based pseudo-s
Kevin Wolz, Elyas Farah, Robert Reischke +2
Multiple cosmological observables, such as the galaxy overdensity or cosmic shear, consist of fields sampled at the discrete positions of astrophysical sources. Recent work has pre…
Probing the Baryon Distribution with Fast Radio Bursts
Manisha Caleb, Jéferson A. S. Fortunato, Steffen Hagstotz +12
Baryonic feedback redistributes matter on small to mid cosmological scales, ultimately limiting inferences from Stage IV galaxy surveys. Direct baryon tracers are crucial for recov…
KiDS-Legacy: The consistency test of the large-scale structure with Bernardeau-Nishimichi-Taruya transform
Shiming Gu, Ziang Yan, Ludovic van Waerbeke +10
We perform the first -cut cosmic shear analysis of the KiDS-Legacy survey. This method uses the Bernardeau-Nishimichi-Taruya (BNT) transform to construct weak-lensing kernels th…
Fast Radio Bursts as Cosmological Probes
Manisha Caleb, Jéferson A. S. Fortunato, Steffen Hagstotz +14
Fast radio bursts (FRBs) are brief, coherent radio pulses of extragalactic origin. They typically last from microseconds to milliseconds and have energies large enough to be visibl…
The Astrophysics of Fast Radio Bursts
Alice P. Curtin, Marcin Gawroński, Jason Hessels +11
Fast radio bursts (FRBs) provide a glimpse of high-energy astrophysical phenomena in other galaxies. They point the way to extreme conditions that are currently undetectable by any…
KiDS-Legacy: Joint analysis of second- and third-order cosmic shear
L. Linke, L. Porth, P. Burger +21
Weak lensing by large-scale structure is a powerful cosmological probe. While most analyses rely on second-order correlations, these are primarily sensitive to the parameter combin…
cloelib: A Flexible Python Library for Computing Cosmological Observables in the Euclid Era
Marco Bonici, Guadalupe Cañas-Herrera, Pedro Carrilho +54
cloelib is a Python library developed to compute cosmological observables within the Cosmology Likelihood for Observables in Euclid (CLOE) ecosystem (cloe-org). As cosmology enters…
Probing baryonic feedback with fast radio bursts: joint analyses with cosmic shear and galaxy clustering
Amy Wayland, David Alonso, Robert Reischke
Cosmological inference from weak lensing (WL) surveys is increasingly limited by uncertainties in baryonic physics, which suppress the non-linear matter power spectrum on small sca…
KiDS-Legacy: WIMP dark matter constraints from the cross-correlation of weak lensing and Fermi-LAT gamma rays
Shiyang Zhang, Hendrik Hildebrandt, Ziang Yan +13
Dark matter dominates the matter content of the Universe, and its properties can be constrained through large-scale structure probes such as the cross-correlation between the unres…
Baryonification III: An accurate analytical model for the dispersion measure probability density function of fast radio bursts

KiDS-1000 cosmic shear reanalysis using MetaCalibration
Mijin Yoon, Henk Hoekstra, Shun-Sheng Li +10
A number of cosmic shear studies have reported results that are in mild tension with the Planck cosmic microwave measurement. To explore if this can be caused by biases in the shea…
Probing baryonic feedback and cosmology with 32-point statistic of FRBs and galaxies
Kritti Sharma, Elisabeth Krause, Vikram Ravi +4
The impact of galaxy formation processes on the matter power spectrum is uncertain and may bias cosmological parameters inferred by large-scale structure surveys. Fast Radio Bursts…
