Cosmology from UNIONS weak lensing profiles of galaxy clusters
Charlie T. Mpetha, James E. Taylor, Yuba Amoura +12
Cosmological information is encoded in the structure of galaxy clusters. In Universes with less matter and larger initial density perturbations, clusters form earlier and have more…
The infall region as a complementary probe to cluster abundance
Charlie T. Mpetha, James E. Taylor, Yuba Amoura +1
Galaxy cluster abundance measurements provide a classic test of cosmology. They are most sensitive to the evolved amplitude of fluctuations, usually expressed as $S_8 = σ_8\sqrt{Ω_…
Constraining cosmological parameters using the splashback radius of galaxy clusters
Roan Haggar, Yuba Amoura, Charlie T. Mpetha +3
Cosmological parameters such as and can be measured indirectly using various methods, including galaxy cluster abundance and cosmic shear. These measurements c…
Halo Growth and Merger Rates as a Cosmological Test
Yuba Amoura, Nicole E. Drakos, Anael Berrouet +1
Dark matter haloes grow at a rate that depends on the value of the cosmological parameters and through the initial power spectrum and the linear growth factor. Wh…
Cluster Assembly Times as a Cosmological Test
Yuba Amoura, Nicole E. Drakos, Anael Berrouet +1
The abundance of galaxy clusters in the low-redshift universe provides an important cosmological test, constraining a product of the initial amplitude of fluctuations and the amoun…
Euclid preparation III. Galaxy cluster detection in the wide photometric survey, performance and algorithm selection
Euclid Collaboration, R. Adam, M. Vannier +56
Galaxy cluster counts in bins of mass and redshift have been shown to be a competitive probe to test cosmological models. This method requires an efficient blind detection of clust…
