Title: Independent cosmological constraints from high-z H II galaxies: new results from VLT-KMOS data
Abstract:
I will show independent constraints of cosmological parameters using the distance estimator based on the established correlation between the Balmer line luminosity, L(H β ), and the velocity dispersion (σ ) for H II galaxies (HIIG). These results are based on new VLT-KMOS high spectral resolution observations of 41 high-z (1.3 ≤ z ≤2.6) HIIG combined with published data for 45 high-z and 107 z ≤0.15 HIIG.
