Using an updated and significantly augmented sample of Cepheid and tip of the red giant branch (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-

THE PULSATION MODE AND DISTANCE OF THE CEPHEID FF AQUILAE [PDF]
Publisher's version/PDFThe determination of pulsation mode and distance for field Cepheids is a complicated problem best resolved by a luminosity estimate.

The Cepheid Distance to the Seyfert 1 Galaxy NGC 4151 [PDF]
We derive a distance of 15.8 ± 0.4 Mpc to the archetypal Seyfert 1 galaxy NGC 4151 based on the near-infrared Cepheid period–luminosity relation and new Hubble Space Telescope multiband imaging.

Toward a renewed Galactic Cepheid distance scale from Gaia and optical interferometry [PDF]
Through an innovative combination of multiple observing techniques and modeling, we are assembling a comprehensive understanding of the pulsation and close environment of Cepheids.

A 1.3% Distance to M33 from Hubble Space Telescope Cepheid Photometry
We present a low-dispersion period–luminosity relation (PL) based on 154 Cepheids in Messier 33 (M33) with Hubble Space Telescope (HST) photometry from the PHATTER survey.

The Cepheid Distance Scale: Recent Progress in Fundamental Techniques [PDF]
This review examines progress on the Pop I, fundamental-mode Cepheid distance scale with emphasis on recent developments in geometric and quasi-geometric techniques for Cepheid distance determination. Specifically I examine the surface brightness method,

A Geometrical 1% Distance to the Short-period Binary Cepheid V1334 Cygni
Cepheid stars play a considerable role as extragalactic distances indicators, thanks to the simple empirical relation between their pulsation period and their luminosity. They overlap with that of secondary distance indicators, such as Type Ia supernovae,

By comparing Cepheid brightnesses with geometric distance measures including Gaia EDR3 parallaxes, most recent analyses conclude metal-rich Cepheids are brighter, quantified as γ ∼ −0.2 mag dex ^−1 .

Cepheid Period‐Radius and Period‐Luminosity Relations and the Distance to the Large Magellanic Cloud
We have used the infrared Barnes-Evans surface brightness technique to derive the radii and distances of 34 Galactic Cepheid variables. Radius and distance results obtained from both versions of the technique are in excellent agreement.

A distance to the galaxy NGC4258 from observations of Cepheid variable stars
Cepheid variable stars pulsate in a way that is correlated with their intrinsic luminosity, making them useful as 'standard candles' for determining distances to galaxies; the potential systematic uncertainties in the resulting distances have been ...
