- W4315706537 abstract "Considering possible solutions to the $S_8$ tension between the Planck cosmic microwave background (CMB) measurement and low-redshift probes, we extended the standard $Lambda$CDM cosmological model by including decay of dark matter (DDM). We first tested the DDM model in which dark matter decays into a form of non-interacting dark radiation. Under this DDM model, we investigated the DDM's impacts on the Sunyaev Zel'dovich effect by varying the decay lifetime, $Gamma^{-1}$, including the background evolution in cosmology and non-linear prescription in the halo mass function. We performed a cosmological analysis under the assumption of this extended cosmological model by combining the latest high-redshift Planck CMB measurement and low-redshift SZ measurement. Our result shows a preference for $Gamma^{-1} sim 200$ Gyr with a lower bound on the decay lifetime of $sim$ 77 Gyr at 95% confidence level. However, the CMB data do not prefer this model, and the $S_8$ tension still remains. Additionally, we tested the other DDM model in which dark matter decays into warm dark matter and dark radiation. This model supports $Gamma^{-1} sim 204$ Gyr to resolve the $S_8$ tension with a lower bound on the decay lifetime of $sim$ 47 Gyr at 95% confidence level." @default.
