The DiskMass Survey. I. Overview
Matthew A. Bershady,Marc Verheijen,R. A. Swaters,David R. Andersen,Kyle B. Westfall,Thomas P. K. Martinsson +5 more
TL;DR: In this article, the authors present a survey of the mass surface density of spiral disks, motivated by outstanding uncertainties in rotation-curve decompositions, and derive precise and accurate line-of-sight stellar velocity dispersions.
The DiskMass Survey VII. The distribution of luminous and dark matter in spiral galaxies
Thomas P. K. Martinsson,Thomas P. K. Martinsson,Marc Verheijen,Kyle B. Westfall,Matthew A. Bershady,David R. Andersen,Rob A. Swaters +6 more
TL;DR: In this article, the authors used measured vertical velocity dispersions of the disk stars to calculate dynamical mass surface densities (Sigma$}${dyn}$) of 30 spiral galaxies, which were carried out to test the maximum disk hypothesis and to quantify properties of their dark-matter halos.

TL;DR: In this paper, a survey of the mass surface-density of spiral disks is presented, motivated by outstanding uncertainties in rotation-curve decompositions, and the authors use integral field spectroscopy to measure stellar and gas kinematics in nearly face-on galaxies.

The DiskMass Survey. VII. The distribution of luminous and dark matter in spiral galaxies
Thomas P. K. Martinsson,Thomas P. K. Martinsson,Marc Verheijen,Kyle B. Westfall,Matthew A. Bershady,David R. Andersen,Rob A. Swaters +6 more
TL;DR: In this paper, the authors used measured vertical velocity dispersions of the disk stars to calculate dynamical mass surface densities, and derived the stellar mass surface density, and thus have absolute measurements of all dominant baryonic components.
SparsePak: A Formatted Fiber Field Unit for The WIYN Telescope Bench Spectrograph. I. Design, Construction, and Calibration
TL;DR: SparsePak as mentioned in this paper is a fiber field unit designed for integral field spectroscopy, which can achieve spectral resolutions of lambda/d lambda ~ 20000 and an area of approximately 140 arcsec^2 m^2 per fiber.
