Cosmological constraints from HII starburst galaxy, quasar angular size, and other measurements

Shulei Cao, Joseph Ryan, Bharat Ratra

We compare the constraints from two (2019 and 2021) compilations of HII starburst galaxy (HIIG) data and test the model-independence of quasar angular size (QSO) data using six spa…

Observational constraints on the cosmological expansion rate and spatial curvature

Joseph Ryan

Observations conducted over the last few decades show that the expansion of the Universe is accelerating. In the standard model of cosmology, this accelerated expansion is attribut…
