Galaxy Zoo: Passive Red Spirals (2009)
Masters, Karen L., Mosleh, Moein, Romer, A. Kathy, Nichol, Robert C., Bamford, Steven P., Schawinski, Kevin, ...
We study the spectroscopic properties and environments of red spiral galaxies found by the Galaxy Zoo project. By carefully selecting face-on, disk dominated spirals we construct a sample of truly...
The Local Velocity Field (2008)
We only see a small fraction of the matter in the universe, but the rest gives itself away by the impact of its gravity. The distortions from pure Hubble flow (or peculiar velocities) that this...
2MTF I. The Tully-Fisher Relation in the 2MASS J, H and K Bands (2007)
Masters, Karen L., Springob, Christopher M., Huchra, John P.
The 2 Micron All-Sky Survey (2MASS) Tully-Fisher Survey (2MTF) aims to measure Tully-Fisher (TF) distances to all bright inclined spirals in the 2MASS Redshift Survey (2MRS). Essential to this...
Mapping Mass in the Local Universe (2007)
We only see a small fraction of the matter in the universe, but the rest gives itself away by the impact of its gravity. Peculiar velocities have the potential to be a powerful tool to trace this...
Springob, Christopher M., Masters, Karen L., Haynes, Martha P., Giovanelli, Riccardo, Marinoni, Christian
We present the SFI++ dataset, a homogeneously derived catalog of photometric and rotational properties and the Tully-Fisher distances and peculiar velocities derived from them. We make use of digital...
Groups of Galaxies in the Two Micron All Sky Redshift Survey (2007)
Crook, Aidan C., Huchra, John P., Martimbeau, Nathalie, Masters, Karen L., Jarrett, Tom, Macri, Lucas M.
We present the results of applying a percolation algorithm to the initial release of the Two Micron All Sky Survey Extended Source Catalog, using subsequently measured redshifts for almost all of the...

SFI++ I: A New I-band Tully-Fisher Template, the Cluster Peculiar Velocity Dispersion and H0 (2006)
Masters, Karen L., Springob, Christopher M., Haynes, Martha P., Giovanelli, Riccardo
The SFI++ consists of ~5000 spiral galaxies which have measurements suitable for the application of the I-band Tully-Fisher (TF) relation. This sample builds on the SCI and SFI samples published in...
Multi-wavelength Study of Galaxy Rotation Curves and its Application to Cosmology (2006)
Saintonge, Amelie, Marinoni, Christian, Masters, Karen L., Haynes, Martha P., Giovanelli, Riccardo, Contini, Thierry
Rotation information for spiral galaxies can be obtained through the observation of different spectral lines. While the Halpha(6563 A) line is often used for galaxies with low to moderate redshifts,...
Multi-wavelength Study of Galaxy Rotation Curves and its Application to Cosmology (2005)
Saintonge, Amelie, Marinoni, Christian, Masters, Karen L., Haynes, Martha P., Giovanelli, Riccardo, Contini, Thierry
Rotation information for spiral galaxies can be obtained through the observation of different spectral lines. While the Halpha(6563 A) line is often used for galaxies with low to moderate redshifts,...
The Arecibo Legacy Fast ALFA Survey: II. Results of Precursor Observations (2005)
Giovanelli, Riccardo, Haynes, Martha P., Kent, Brian R., Perillat, Philip, Catinella, Barbara, Hoffman, G. Lyle, ...
In preparation for the full Arecibo Legacy Fast ALFA extragalactic HI survey, precursor observations were carried out in Aug--Sep 2004 with the 7-beam Arecibo L-band feed array (ALFA) receiver system...
Cosmology in the Very Local Universe - Why Flow Models Matter (2005)
While much of the focus of observational cosmology is on the high redshift universe it is important not to neglect the very local universe as a source of cosmological information. The inner profiles...

The Impact of Distance Uncertainties on Local Luminosity and Mass Functions (2004)
Masters, Karen L., Haynes, Martha P., Giovanelli, Riccardo
In order to investigate discrepancies between recent published estimates of the the HI mass function (HIMF), we explore the impact of distance uncertainties on the derivation of the faint end slope...
Internal Extinction in Spiral Galaxies in the Near Infrared (2003)
Masters, Karen L., Giovanelli, Riccardo, Haynes, Martha P.
In order to study the effects of internal extinction in spiral galaxies we search for correlations of near infrared (NIR) photometric parameters with inclination. We use data from the 2 Micron...
The Elliptical Galaxy formerly known as the Local Group: Merging the Globular Cluster Systems (2000)
Forbes, Duncan A., Masters, Karen L., Minniti, Dante, Barmby, Pauline
Prompted by a new catalogue of M31 globular clusters, we have collected together individual metallicity values for globular clusters in the Local Group. Although we briefly describe the globular...
