Cosmological constraints from current and upcoming galaxy cluster surveys are limited by
the accuracy of cluster mass calibration. In particular, optically identified galaxy clusters are …

We present the mass calibration for galaxy clusters detected with the AMICO code in KiDS
DR3 data. The cluster sample comprises 7000 objects and covers the redshift range 0.1<< …

Robust galaxy cluster mass estimates are fundamental for constraining cosmological
parameters from counts. For this reason, it is essential to search for tracers that, independent …

Context. Samples of galaxy clusters allow us to better understand the physics at play in
galaxy formation and to constrain cosmological models once the mass, position (for …

ABSTRACT We present a new (2+ 1) D galaxy cluster finder based on photometric redshifts
called Wavelet Z Photometric (WaZP) applied to DES first year (Y1A1) data. The results are …

Galaxy clusters are important probes for both cosmology and galaxy formation physics. We
test the cosmological, hydrodynamical FLAMINGO simulations by comparing to observations …

We introduce a galaxy cluster mass observable, μ⋆, based on the stellar masses of cluster
members, and we present results for the Dark Energy Survey (DES) Year 1 (Y1) …

To understand how well galaxies, gas, and intracluster stars trace dark matter in and around
galaxy clusters, we use the IllustrisTNG cosmological hydrodynamical simulation and …

The cluster mass–richness relation (MRR) is an observationally efficient and potentially
powerful cosmological tool for constraining the matter density Ω m and the amplitude of …

Galaxy pairs constitute the initial building blocks of galaxy evolution, which is driven through
merger events and interactions. Thus, the analysis of these systems can be valuable in …
