The Hubble relation based on the HII galaxies as an efficient tool to understand the mechanism of late Dark Energy cosmic acceleration

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.
