Cosmological constraints from higher-redshift gamma-ray burst, HII starburst galaxy, and quasar (and other) data

Shulei Cao, Joseph Ryan, Narayan Khadka +1

We use higher-redshift gamma-ray burst (GRB), HII starburst galaxy (HIIG), and quasar angular size (QSO-AS) measurements to constrain six spatially flat and non-flat cosmological m…
