| dc.description | I have selected a sample of 504 HII like-starburst galaxies according to the equivalent
widths in their emission lines in a range of redshift of 0.1 < z < 3.4 from the literature,
in order to assess the validity of the L(HB) - g relation at high redshift and its use
as an accurate distance estimator. The physical parameters for the sample at high
redshift, within the uncertainties, are consistent with the ones for the HIIGx at low
redshift. This suggests that the physical properties for HIIGx at low and high redshift
are similar.
By combining our sample at high redshift with the local sample of HIIGx from Chávez
et al. (2014), I find an evident flattening that starts at approximately log(g) = 1:8 km
s-1 in the L(HB) - g relation. This flattening has an interesting application since it
leads to a kind of standard candle for those HIIGx with log(g) > 1:8 km s-1. This
flattening or the existence of an upper limit in the luminosity of HIIGx has not been
reported before. Applying this new HIIGx standard candle method to the high redshift
sample we obtain good restrictions on the cosmological parameters solution space.
The combination of our sample at high redshift with the local sample of 156 (HIIGx
and GEHRs) dramatically improves the constraints on the plane (nm, w0), which are
consistent with the results from SNeIa.
These results are surprisingly good considering the high uncertainties in the data at
high redshift, therefore we expect better constraints on the plane (nm, w0) using high
quality data from high resolution spectrographs at 8 m class telescopes. | |
