Highlight: The Hubble Constant Anchor Galaxy NGC 4258: Metallicity
and Distance from Blue Supergiants Stars
Highlight: An Independent New Determination of the Hubble Constant
- the SNIa Host Galaxy M101 and the Distance from Blue Supergiants
Highlight: An Additional New Independent Determination of the Hubble Constant
- Calibration of the Tully-Fisher Relationship with Galaxy Distances
from Blue Supergians
Highlight: Mass - Metallicity Relationship (MZR) of Star Forming Galaxies
This is the first MZR based solely on accurate stellar spectroscopy. The
results are obtained from the spectral analysis of young massive stars
either as individuals or in a population synthesis approach.
