Riess, Adam G., Macri, Lucas, Casertano, Stefano, Sosey, Megan, Lampeitl, Hubert, Ferguson, Henry C., ...
We report observations of 240 Cepheid variables obtained with the Near Infrared Camera (NICMOS) through the F160W filter on the Hubble Space Telescope (HST). The Cepheids are distributed across six...
Cepheid Calibrations of Modern Type Ia Supernovae:Implications for the Hubble Constant (2009)
Riess, Adam G., Macri, Lucas, Li, Weidong, Lampeitl, Hubert, Casertano, Stefano, Ferguson, Henry C., ...
This is the first of two papers reporting measurements from a program to determine the Hubble constant to 5% precision from a refurbished distance ladder. We present new observations of 110 Cepheid...
Estimation of the Hubble Constant and Constraint on Descriptions of Dark Energy (2009)
Greenhill, Lincoln, Humphreys, Elizabeth, Hu, Wayne, Macri, Lucas, Murphy, David, Masters, Karen, ...
Joint analysis of Cosmic Microwave Background, Baryon Acoustic Oscillation, and supernova data has enabled precision estimation of cosmological parameters. New programs will push to 1% uncertainty in...
Orosz, Jerome A., McClintock, Jeffrey E., Narayan, Ramesh, Bailyn, Charles D., Hartman, Joel D., Macri, Lucas, ...
This Supplementary Information provides details about the spectral extraction (crowding issues and the removal of nebular lines), a discussion about the distance to M33, a model for the O-star wind...
A 15.65-solar-mass black hole in an eclipsing binary in the nearby spiral galaxy M 33 (2007)
Orosz, Jerome A., McClintock, Jeffrey E., Narayan, Ramesh, Bailyn, Charles D., Hartman, Joel D., Macri, Lucas, ...
The DIRECT project aims to determine direct distances to two important galaxies in the cosmological distance ladder -- M31 and M33 -- using detached eclipsing binaries (DEBs) and Cepheids. I present...
Ferrarese, Laura, Ford, Holland C., Huchra, John, Kennicutt, Robert C., Mould, Jeremy R., ...
We present a compilation of Cepheid distance moduli and data for four secondary distance indicators that employ stars in the old stellar populations: the planetary nebula luminosity function (PNLF),...
The Hubble Constant from the HST Key Project on the Extragalactic Distance Scale (1999)
Ferrarese, Laura, Gibson, Brad, Kelson, Daniel, Sakai, Shoko, Mould, Jeremy, Freedman, Wendy, ...
The final efforts of the HST Key Project on the Extragalactic Distance Scale are presented. Four distance indicators, the Surface Brightness Fluctuation method, the Fundamental Plane for early-type...
Ferrarese, Laura, Mould, Jeremy R., Kennicutt, Robert C., Huchra, John, Ford, Holland C., ...
A Cepheid-based calibration is derived for four distance indicators that utilize stars in the old stellar populations: the tip of the red giant branch (TRGB), the planetary nebula luminosity function...
Prosser, Charles F., Kennicutt, Robert C., Bresolin, Fabio, Saha, Abhijit, Sakai, Shoko, ...
We report on the detection of Cepheids and the first distance measurement to the spiral galaxy NGC 1326-A, a member of the Fornax cluster of galaxies. We have employed data obtained with the Wide...
Sakai, Shoko, Ferrarese, Laura, Kennicutt, Robert C., Graham, John A., Silbermann, N. A., Mould, Jeremy R., ...
The distance to NGC 3319 has been determined from Cepheid variable stars as part of the Hubble Space Telescope Key Project on the Extragalactic Distance Scale. Thirteen and four epochs of...
