Morphology, Environment, and the HI Mass Function
Christopher M. Springob, Martha P. Haynes, Riccardo Giovanelli
We exploit a large, complete optical diameter and HI flux limited sample of spiral galaxies with types later than S0a to derive a robust measurement of the HI mass function (HIMF)…
Rotationally Supported Virgo Cluster Dwarf Elliptical Galaxies: Stripped Dwarf Irregular Galaxies?
L. van Zee, E. D. Skillman, M. P. Haynes
New observations of 16 dwarf elliptical galaxies in the Virgo Cluster indicate that at least seven dEs have significant velocity gradients along their optical major axis, with typi…
Detection of 21 Centimeter HI Absorption at z = 0.78 in a Survey of Radio Continuum Sources
Jeremy Darling, Riccardo Giovanelli, Martha P. Haynes +2
We report the detection of a deep broad HI 21 cm absorption system at z = 0.78 toward the radio source [HB89] 2351+456 (4C+45.51) at z = 1.992. The HI absorption was identified in…
The Impact of Distance Uncertainties on Local Luminosity and Mass Functions
Karen L. Masters, Martha P. Haynes, Riccardo Giovanelli
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 th…
M/L, H-alpha Rotation Curves, and HI Measurements for 329 Nearby Cluster and Field Spirals: I. Data
Nicole P. Vogt, Martha P. Haynes, Terry Herter +1
A survey of 329 nearby galaxies (redshift z < 0.045) has been conducted to study the distribution of mass and light within spiral galaxies over a range of environments. The 18 obse…
M/L, H-alpha Rotation Curves, and HI Measurements for 329 Nearby Cluster and Field Spirals: III. Evolutionin Fundamental Galaxy Parameters
Nicole P. Vogt, Martha P. Haynes, Riccardo Giovanelli +1
We have conducted a study of optical and HI properties of spiral galaxies (size, luminosity, H-alpha flux distribution, circular velocity, HI gas mass) to investigate causes (e.g.,…
