The authors' main claim However, the resulting GRB data constraints on the current value of the nonrelativistic matter density parameter, $\Omega_{m0}$, are in $>2\sigma$ tension with those from a joint analysis of better-established Hubble parameter [$H(z)$] and baryon acoustic oscillation (BAO) data for most of the cosmological models we consider, indicating that these GRB data cannot be jointly used with better-established $H(z)$ + BAO data to constrain cosmological parameters.

By using gamma-ray burst (GRB) data to simultaneously constrain Amati correlation parameters and cosmological parameters in six spatially-flat and nonflat dark energy cosmological models, we show that an updated 220 GRB version of the Jia et al. [Mon. Not. R. Astron. Soc. 516, 2575 (2022)] GRB data compilation are standardizable through the Amati correlation and so can be used for cosmological analyses.

The GRB data from the standard Amati correlation only give a lower bound limit on the present matter density parameter $\Omega_{\mathrm{m0}}$, while the GRBs from the improved Amati correlation constrain the $\Omega_{\mathrm{m0}}$ with the $68\%$ confidence level to be $0.308^{+0.066}_{-0.230}$ and $0.307^{+0.057}_{-0.290}$ in the $\Lambda$CDM and $w$CDM models, respectively, which are consistent very well with those given by other current popular observational data including BAO, CMB and so on.

We consider the log-likelihood [equation] where $E_p,i$ is the spectral peak energy and $E_iso,i$ is the isotropic equivalent radiated energy of the $i^th$ GRB, and $s_i$ denotes the associated error, [equation] The data set [ref] provides redshifts, $z_i$, $E_p,i$ and its error $σ_E_p,i$, along with the measured bolometric fluence $S_bolo, i$ and its error $σ_S_bolo, i$.

The J220 intrinsic scatter constraints $σ_int∼0.39$ are fairly consistent with the A118 constraints reported in Ref. [ref] (and A118 constraints here), while the A102 constraints are $∼0.52$ and the joint A220 constraints are between the two at $∼0.46$, indicating that A118 is of significantly better quality than A102.
