A Novel Framework for Modeling Weakly Lensing Shear Using Kinematics and Imaging at Moderate Redshift
Brian DiGiorgio, Kevin Bundy, Kyle B. Westfall +2
Kinematic weak lensing describes the distortion of a galaxy's projected velocity field due to lensing shear, an effect recently reported for the first time by Gurri et al. based on…
A precise extragalactic test of General Relativity
Thomas E. Collett, Lindsay J. Oldham, Russell J. Smith +7
Einstein's theory of gravity, General Relativity, has been precisely tested on Solar System scales, but the long-range nature of gravity is still poorly constrained. The nearby str…
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…
Galaxy Disks are Submaximal
Matthew A. Bershady, Thomas P. K. Martinsson, Marc A. W. Verheijen +3
We measure the contribution of galaxy disks to the overall gravitational potential of 30 nearly face-on intermediate-to-late-type spirals from the DiskMass Survey. The central vert…
