MNRAS, 493[4]:4728–4747, Feb. 2020.

The power spectrum measured by Mertens et al. (2020) has been used to rule out certain cosmological models with extreme IGM parameters by Ghara et al. (2020). Figure 4 shows the likelihood analysis of this power spectrum in term of IGM properties from the paper.

4- Constraining Cosmological models with The LOFAR EoR Upper

Figure 4: This figure shows constraints fiveIGM parameters, assuming a uniform Tspin scenario from an MCMC analysis using the LOFAR upper limit shown in the left panel. The color-bar shows the probability that models are ruled out. The solid and dashed curves show the 68% and 95% credible intervals of the ruled out models. The diagonal panels show the marginalized probability distribution by which each parameter value as used in the MCMC analysis is ruled out (Ghara et al. 2020)
