dc.description | We propose to use H II galaxies to trace the redshift-distance relation, by means of
their L(Hβ) - δ correlation, in an attempt to constrain the dark energy equation of
state parameter solution space, as an alternative to the cosmological use of type Ia
supernovae.
In order to use effectively high redshift H II galaxies as probes of the dark energy
equation of state parameter, we must reassess the L(Hβ) - δ distance estimator, minimising
the observational uncertainties and taking care of the possible associated systematics,
such as stellar age, gas metallicity, reddening, environment and morphology.
For a sample of 128 local (0:02 ≲ z ≲ 0:2) compact H II galaxies with high equivalent
widths of their Balmer emission lines we obtained ionised gas velocity dispersion
from high S/N, high-dispersion spectroscopy (Subaru-HDS and ESO VLT-UVES) and
integrated Hβ fluxes from low dispersion wide aperture spectrophotometry. | |
