Constraining primordial non-Gaussianity and energy injection with the thermal Sunyaev-Zeldovich effect and integrated Sachs-Wolfe effect cross-correlation

Ayodeji Ibitoye, Yin-Zhe Ma, Prabhakar Tiwari

Constraining primordial non-Gaussianity (PNG) provides key insights into the physics of cosmic inflation and the initial conditions of the Universe, which remain central topics in…

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…
