Constraints on dark energy from H II starburst galaxy apparent magnitude versus redshift data

TL;DR

This study uses H II starburst galaxy data to constrain dark energy models, providing results consistent with other methods but with less precision.

Contribution

It introduces the use of H II galaxy apparent magnitude-redshift data for dark energy parameter constraints, expanding observational approaches.

Findings

Constraints are consistent with other data sets.

Results are less restrictive than the tightest current constraints.

Supports the viability of H II galaxies as cosmological probes.

Abstract

In this paper we use H II starburst galaxy apparent magnitude versus redshift data from Siegel et al. (2005) to constrain dark energy cosmological model parameters. These constraints are generally consistent with those derived using other data sets, but are not as restrictive as the tightest currently available constraints.
