The Extragalactic Distance Scale without Cepheids (2008)
Distances of galaxies in the Hubble Space Telescope Key Project are based on the Cepheid period-luminosity relation. An alternative basis is the tip of the red giant branch. Using archival HST data,...
Bernard, Jean-Philippe, Reach, William T., Paradis, Deborah, Meixner, Margaret, Paladini, Roberta, Kawamura, Akiko, ...
The goal of this paper is to present the results of a preliminary analysis of the extended infrared (IR) emission by dust in the interstellar medium (ISM) of the Large Magellanic Cloud (LMC). We...
A point source survey of M31 with the Spitzer Space Telescope (2008)
Mould, Jeremy, Barmby, Pauline, Gordon, Karl, Willner, S. P., Ashby, M. L. N., Gehrz, R. D., ...
We explore the stellar population of M31 in a Spitzer Space Telescope survey utilizing IRAC and MIPS observations. Red supergiants are the brightest objects seen in the infrared; they are a prominent...
Interim Report On The Hst Key Project To Measure H (2007)
With an interim calibration based upon half the Key Project's galaxies, the Tully-Fisher relation, the (Dn ; oe) relation and type II supernovae yield H 0 = 73 \Sigma 10 km/sec/Mpc. I....
Meixner, Margaret, Gordon, Karl D., Indebetouw, Remy, Hora, Joseph L., Whitney, Barbara, Blum, Robert, ...
We are performing a uniform and unbiased, ~7x7 degrees imaging survey of the Large Magellanic Cloud (LMC), using the IRAC and MIPS instruments on board the Spitzer Space Telescope in order to survey...
Le Floc'h, Emeric, Papovich, Casey, Dole, Hervé, Bell, Eric F., Lagache, Guilaine, Rieke, George H., ...
We analyze a sample of ~2600 Spitzer MIPS 24 mum sources brighter than ~80 muJy and located in the Chandra Deep Field-South to characterize the evolution of the comoving infrared (IR) energy density...
Red thick disks of nearby galaxies (2004)
Edge on systems reveal the properties of disk galaxies as a function of height, z, above the plane. Four local edge-on galaxies, that are close enough to have been resolved into stars by the Hubble...
Limits on Hubble Constant from the Distance of M100 (2004)
Mould, Jeremy, Huchra, John P., Bresolin, Fabio, Ferrarese, Laura, Ford, Holland C., Freedman, Wendy L., ...
We examine the consequences of a 17 Mpc M100 distance, questioning its consistency with supernova and other distances.
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...
Madore, Barry F., Freedman, Wendy L., Silbermann, N., Harding, Paul, Huchra, John, Mould, Jeremy, ...
Using the Hubble Space Telescope (HST) 37 long-period Cepheid variables have been discovered in the Fornax Cluster spiral galaxy NGC 1365. The resulting V and I period-luminosity relations yield a...
