Star clusters at z=9.6 combined with local globular cluster ages give H0=70(+27,-16) km/s/Mpc and Omega_m=0.33(+0.37,-0.21), with a forecast that ~300 clusters could reach 4% precision.

abstract
VANDELS is a deep spectroscopic survey, performed with the VIMOS instrument at VLT, aimed at studying in detail the physical properties of high-redshift galaxies. VANDELS targeted about 2100 sources at 1<z<6.5 in the CANDELS Chandra Deep-Field South (CDFS) and Ultra-Deep Survey (UDS) fields. In this paper we present the public release of the spectroscopic measurement catalogues from this survey, featuring emission and absorption line centroids, fluxes, and rest-frame equivalent widths obtained through a Gaussian fit, as well as a number of atomic and molecular indices (e.g. Lick) and continuum breaks (e.g. D4000), and including a correction to be applied to the error spectra. We describe the measurement methods and the validation of the codes that were used.

Cosmic CORALS: Timing the Universe with high-z star clusters
Star clusters at z=9.6 combined with local globular cluster ages give H0=70(+27,-16) km/s/Mpc and Omega_m=0.33(+0.37,-0.21), with a forecast that ~300 clusters could reach 4% precision.
