A Comparison of Halpha and Stellar Scale Lengths in Virgo and Field Spirals
R. A. Koopmann, M. P. Haynes, B. Catinella
The scale lengths of the old stars and ionized gas distributions are compared for similar samples of Virgo Cluster members and field spiral galaxies via Halpha and broad R-band sur…
Multi-wavelength Study of Galaxy Rotation Curves and its Application to Cosmology
Amelie Saintonge, Christian Marinoni, Karen L. Masters +3
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 m…
Oxygen and Nitrogen in Leo A and GR 8
L. van Zee, E. D. Skillman, M. P. Haynes
We present elemental abundances for multiple HII regions in Leo A and GR 8 obtained from long slit optical spectroscopy of these two nearby low luminosity dwarf irregular galaxies.…
Galaxy Peculiar Velocities and Infall onto Groups
M. L. Ceccarelli, C. Valotto, D. G. Lambas +3
We perform statistical analyses to study the infall of galaxies onto groups and clusters in the nearby Universe. The study is based on the UZC and SSRS2 group catalogs and peculiar…
The Arecibo Legacy Fast ALFA Survey: I. Science Goals, Survey Design and Strategy
Riccardo Giovanelli, Martha P. Haynes, Brian R. Kent
The recently initiated Arecibo Legacy Fast ALFA (ALFALFA) survey aims to map 7000 square degrees of the high galactic latitude sky visible from Arecibo, providing a HI line spectra…
The Arecibo Legacy Fast ALFA Survey: II. Results of Precursor Observations
Riccardo Giovanelli, Martha P. Haynes, Brian R. Kent +17
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 (AL…
