Assembly bias and the redshift evolution of intrinsic alignments for LRGs

A. Herle, N. E. Chisari, H. Hoekstra +1

The intrinsic alignment (IA) of galaxies is one of the main contaminants to the weak lensing shear signal. Efforts to model it often assume that the alignment strength depends only…

Calibrating baryonic feedback with weak lensing and fast radio bursts

Robert Reischke, Dennis Neumann, Klara Antonia Bertmann +2

One of the key limitations of large-scale structure surveys of the current and future generation, such as Euclid, LSST-Rubin or Roman, is the influence of feedback processes on the…

Intrinsic alignments of galaxies in multiple projections

Marloes van Heukelum, Dennis Neumann, Marta Garcia Escobar +2

Intrinsic alignments of galaxies are measured and modelled to gain cosmological information, to further understand the interactions between galaxies and to mitigate their effects o…

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…

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…
