Reddening maps of the Magellanic Clouds using spectral energy distribution fitting of red giants
H. Netzel, G. PietrzyÅski, M. Górski +9
Robust reddening maps of the Large and Small Magellanic Clouds (LMC/SMC) are crucial for a wide range of astrophysical studies, including the calibration of the cosmic distance lad…
Toward Early-type Eclipsing Binaries as Extragalactic Milestones: First Calibration of the SBCR from O- and B-type Stars in Detached Eclipsing Binaries
Mónica Taormina, G. PietrzyÅski, B. Pilecki +4
To measure precise distances beyond the Magellanic Clouds and determine an accurate value of the Hubble constant, eclipsing binary systems composed of early-type stars can play a c…
Period-Luminosity Relations, projection factor and radii of Anomalous Cepheids
Piotr Wielgórski, Grzegorz PietrzyÅski, Wolfgang Gieren +24
Anomalous Cepheids are radially pulsating stars observed in dwarf galaxies, the Galactic bulge and halo, and globular clusters. Similarly to other radially pulsating stars, they ca…
Surface brightness-colour relations of Milky Way and Magellanic Clouds classical Cepheids based on Gaia magnitudes
M. C. Bailleul, N. Nardetto, V. Hocdé +12
Aims: We derive SBCRs for classical Cepheids in the Milky Way and in the Magellanic Clouds using the photometric data available in the Gaia database, and we quantify the metallicit…
The Local Distance Network: a community consensus report on the measurement of the Hubble constant at 1% precision
H0DN Collaboration, Stefano Casertano, Gagandeep Anand +35
The direct, empirical determination of the local value of the Hubble constant (H0) has markedly advanced thanks to improved instrumentation, measurement techniques, and distance es…
Period-Luminosity Relations for Galactic Type II Cepheids in the Sloan bands
W. Narloch, G. Hajdu, G. Pietrzynski +7
Type II Cepheids (T2Ceps), alongside RR Lyrae stars, serve as important distance indicators for old population II stars due to their period-luminosity (PL) relations. However, stud…
