Ultra-long-period Cepheids as Standard Candles from Gaia to Rubin-LSST
The Astrophysical Journal Supplement SeriesAn analysis of the properties of ultra-long-period Cepheids (ULPs) could significantly contribute to understanding the Hubble constant tension, e.g., the current discrepancy between determinations based on local distance indicators and those relying on ...

On Cepheid Distances in the $${H}_{0}$$ Measurement
Classical Cepheids were the first stellar standard candles and have played a crucial role for astronomical distance measurements ever since the discovery of the Leavitt law (period-luminosity relation). Enormous improvements in distance accuracy have been achieved since Hertzsprung's first application of Leavitt's law to measure the distance to the ...

Highlights on eclipsing binary variables from Araucaria Project
EPJ Web of Conferences, 2015 The Araucaria Project, which main goal is to provide precise determination of the cosmic distance scale, has recently made a set of discoveries involving variable stars in binary systems. Among these discoveries we highlight three: 1% precise measurement

NEW CATALOG OF DISTANCES AND LIGHT CURVE PARAMETERS OF CLASSICAL CEPHEIDS
Odessa Astronomical Publications, 2017 A new version of the catalogue of distances and light-curve parameters for galactic classical Cepheids is presented. The catalogue lists amplitudes, magnitudes at maximum light, and intensity means for 515 stars in UBVRI filters of the Johnson system ...

The Astrophysical JournalThe TRGB−SBF Project team is developing an independent distance ladder using a geometrical calibration of the tip of the red giant branch (TRGB) method in elliptical galaxies that can, in turn, be used to set the surface brightness fluctuation (SBF ...

The Astrophysical JournalWe cross-check the Hubble Space Telescope (HST) Cepheid/Type Ia supernova (SN Ia) distance ladder, which yields the most precise local H _0 , against early James Webb Space Telescope (JWST) subsamples (∼1/4 of the HST sample) from SH0ES and CCHP ...

The TRGB-SBF Project. I. A Tip of the Red Giant Branch Distance to the Fornax Cluster with JWST
The Astrophysical JournalDifferences between the local value of the Hubble constant measured via the distance ladder versus the value inferred from the cosmic microwave background with the assumption of the standard ΛCDM model have reached over 5 σ significance.
