We present new high spectral resolution observations of high-z (1.3 ≤ z ≤2.5) H II galaxies (HIIG) obtained with both MOSFIRE at the Keck Observatory and KMOS at the VLT Observatory. These data, combined with already published data for another high-z and local HIIG (z ≤ 0.15), are used to obtain new independent cosmological results using the distance estimator based on the established correlation between the Balmer emission line velocity dispersion and luminosity for HIIG.
