DOI: 10.1088/1475-7516/2022/01/018
Abstract: We explore constraints on dark energy and modified gravity with forecasted 21cm intensity mapping measurements using the Effective Field Theory approach. We construct a realistic mock data set forecasting a low redshift 21cm signal power… read more here.

Abstract: By focusing on the simple $w\neq-1$ extension to $\Lambda$CDM, we assess which epoch(s) possibly source the $H_0$-tension. We consider Cosmic Microwave Background (CMB) data in three possible ways: $i)$ complete CMB data; $ii)$ excluding the… read more here.

DOI: 10.1103/physrevd.104.023523
Abstract: We investigate the H0 tension in a range of extended model frameworks beyond the standard ΛCDM without the data from the cosmic microwave background (CMB). Specifically, we adopt the data from baryon acoustic oscillations, big… read more here.
