Spatial Age Distribution of Classical Cepheids in Spiral Galaxies: The Cases of M31 and M33

The Astrophysical Journal Letters
Classical Cepheids can be used as age indicators due to well-established period–age and period–age–color relations. G. De Somma et al. refined these relations by including a metallicity term and different mass–luminosity assumptions.

The Gaia Parallax Discrepancy for the Cluster Pismis 19 and Separating δ Scutis from Cepheids

The Astrophysical Journal
Pre-Gaia distances for the open cluster Pismis 19 disagree with Gaia parallaxes. A Two Micron All Sky Survey (2MASS) JK _s red clump distance was therefore established for Pismis 19 (2.90 ± 0.15 kpc), which reaffirms that zero-point corrections for Gaia ...

Tip of the Red Giant Branch Distances with JWST. II. I-band Measurements in a Sample of Hosts of 10 Type Ia Supernova Match HST Cepheids

The Astrophysical Journal
The Hubble Tension, a >5 σ discrepancy between direct and indirect measurements of the Hubble constant ( H _0 ), has persisted for a decade and motivated intense scrutiny of the paths used to infer H _0 .

Ultra-long-period Cepheids as Standard Candles from Gaia to Rubin-LSST

The Astrophysical Journal Supplement Series
An 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 ...
