The Cosmic Radio Dipole and Observer Effects in SKA all-sky surveys

D. Bertacca, L. Böhme, B. Bottazzi Baldi +13

The Square Kilometre Array (SKA) will observe our Universe on the largest scales and so enable the study of fundamental assumptions in cosmology, such as cosmic homogeneity and iso…

Constraining Quintessence Models with ISW-tSZ Cross-Correlations: A Comparative Analysis of Thawing, Tracker, and Scaling-Freezing Dynamics

Ayodeji Ibitoye, Shiriny Akthar, Md. Wali Hossain +5

We present constraints on quintessence dark energy models using the observational detection of the Integrated Sachs-Wolfe (ISW)--thermal Sunyaev-Zeldovich (tSZ) cross-correlation d…

The Hydrostatic Mass Bias and the $σ_{8}$ Tension: A Multi-Probe Forecast for Stage-IV/V Surveys

Ayodeji Ibitoye, Prabhakar Tiwari, Qi Xiong +1

The hydrostatic mass bias ( $b_{HSE}$ ) is a leading systematic uncertainty in cluster cosmology and a principal source of degeneracy with $σ_{8}$ and $Ω_{m}$ . We investigate th…
