The metallicity and distance of Leo A from blue supergiants
Miguel A. Urbaneja, Fabio Bresolin, Rolf-Peter Kudritzki
We have obtained high-quality spectra of blue supergiant candidates in the dwarf irregular galaxy Leo A with the Low Resolution Imaging Spectrometer at the Keck I telescope. From t…
The Araucaria Project: Improving the cosmic distance scale
The Araucaria Project, :, G. Pietrzyński +21
The book consists of a number of short articles that present achievements of the Araucaria members, collaborators, and friends, in various aspects of distance determinations and re…
Spatially-resolved properties of the ionized gas in the HII galaxy J084220+115000
D. Fernández-Arenas, E. Carrasco, R. Terlevich +20
We present a spatially resolved spectroscopic study for the metal poor HII galaxy J084220+115000 using MEGARA Integral Field Unit observations at the Gran Telescopio Canarias. We e…
The metallicity and distance of NGC 2403 from blue supergiants
Fabio Bresolin, Rolf-Peter Kudritzki, Miguel A. Urbaneja
We present the first quantitative spectral analysis of blue supergiant stars in the nearby galaxy NGC 2403. Out of a sample of 47 targets observed with the LRIS spectrograph at the…
Cosmological Constraints using the newest VLT-KMOS HII Galaxies and the full Planck CMB spectrum
Pavlina Tsiapi, Spyros Basilakos, Manolis Plionis +7
We present novel cosmological constraints based on a joint analysis of our HII galaxies (HIIG) Hubble relation with the full Planck Cosmic Microwave Background anisotropy spectrum…
Using newest VLT-KMOS HII Galaxies and other cosmic tracers to test the CDM tension
Ahmad Mehrabi, Spyros Basilakos, Pavlina Tsiapi +8
We place novel constraints on the cosmokinetic parameters by using a joint analysis of the newest VLT-KMOS HII galaxies (HIIG) with the Supernovae Type Ia (SNIa) Pantheon sample. W…
