The Stability of Galaxy Disks
Kyle B. Westfall, David R. Andersen, Matthew A. Bershady +3
We calculate the stellar surface mass density (Sigma_*) and two-component (gas+stars) disk stability (Q_RW) for 25 late-type galaxies from the DiskMass Survey. These calculations a…
The DiskMass Survey. VII. The distribution of luminous and dark matter in spiral galaxies
Thomas P. K. Martinsson, Marc A. W. Verheijen, Kyle B. Westfall +3
We present dynamically-determined rotation-curve mass decompositions of 30 spiral galaxies, which were carried out to test the maximum-disk hypothesis and to quantify properties of…
The DiskMass Survey. VI. Gas and stellar kinematics in spiral galaxies from PPak integral-field spectroscopy
Thomas P. K. Martinsson, Marc A. W. Verheijen, Kyle B. Westfall +4
We present ionized-gas (OIII) and stellar kinematics (velocities and velocity dispersions) for 30 nearly face-on spiral galaxies out to as much as three disk scale lengths (h_R). T…
