Milky Way Classical Cepheid Distances from Calibrated Infrared Period–Luminosity–Metallicity Relations

The Astrophysical Journal
Classical Cepheids (DCEPs) serve as fundamental standard candles for measuring cosmic distances and investigating the structure and evolution of the Milky Way disk.

Paediatric and Adult Solid Tumours Exhibiting NTRK Gene Fusions in Australia, 2020–2044: A Population‐Based Statistical Modelling Study

Cancer Medicine, Volume 15, Issue 5, May 2026.
We projected 1‐year to 5‐year cancer prevalence associated with NTRK gene fusions in Australia, from 2020 to 2044, for all paediatric cancers combined (age < 18 years at diagnosis), all adult solid cancers combined, 18 cancer types/groups, and 5 cancer sub‐types relevant to current Australian government subsidies of TRK inhibitors.

Systematics in the Cepheid and TRGB Distance Scales: Metallicity Sensitivity of the Wesenheit Leavitt Law

, 2023
Using an updated and significantly augmented sample of Cepheid and TRGB distances to 28 nearby spiral and irregular galaxies, covering a wide range of metallicities, we have searched for evidence of a correlation of the zero-point of the Cepheid Period ...

On the Distance of Magellanic Clouds: First Overtone Cepheids [PDF]

The Astrophysical Journal, 2002
We present a detailed comparison between predicted and empirical PL_{I,K} relations and Wesenheit function for Galactic and Magellanic Clouds (MCs) First Overtone (FO) Cepheids. We find that zero-points predicted by Galactic Cepheid models based on a noncanonical (mild overshooting) Mass-Luminosity (ML) relation are in very good agreement with ...

Chicago–Carnegie Hubble Program: A Multiwavelength Search for the Effects of Metallicity on the Cepheid Distance Scale. II. Theoretical Models and Synthetic Spectra

The Astrophysical Journal
This is the second of two papers exploring the effects of metallicity on the multiwavelength properties of Cepheids in terms of their multiwavelength period–luminosity (PL) relations, impacting their use as extragalactic distance indicators and ...

The Cepheid Extragalactic Distance Scale: Past, Present and Future

, 2023
Cepheids have been the cornerstone of the extragalactic distance scale for a century. With high-quality data, these luminous supergiants exhibit a small dispersion in their Leavitt (period-luminosity) relation, particularly at longer wavelengths, and few

Discovery of the Longest-period Classical Cepheid in the Milky Way

The Astrophysical Journal Letters
We report the discovery of the classical Cepheid OGLE-GD-CEP-1884 (= GDS_J1535467-555656) with the longest pulsation period known in our Galaxy. The period of 78.14 days is nearly 10 days longer than that of the previous record-holding Cepheid, S ...

The Cepheid Distance to the Narrow-line Seyfert 1 Galaxy NGC 4051

, 2021
We derive a distance of D = 16.6 +/- 0.3 Mpc (mu = 31.10 +/- 0.04 mag) to the archetypal narrow-line Seyfert 1 galaxy NGC 4051 based on Cepheid period-luminosity relations and new Hubble Space Telescope multiband imaging.
