We apply the Tremaine-Weinberg method of pattern speed determination to data cubes of CO emission in six spiral galaxies from the BIMA Survey of Nearby Galaxies, each with an interstellar medium dominated by molecular gas. We compare derived pattern speeds with estimates based on other methods, usually involving the identification of a predicted behavior at one or more resonances of the pattern(s). In two cases (NGC 1068 and NGC 4736), we find evidence for a central bar pattern speed that is… Expand
PATTERN SPEEDS OF SPIRAL GALAXIES USING THE TREMAINE-WEINBERG METHOD
Long-lasting spiral structure in galaxies is established when density waves form a pattern that rotates at a constant angular frequency Ωp, the pattern speed. This quantity, critical to understandingExpand
PATTERN SPEEDS OF BARS AND SPIRAL ARMS FROM Hα VELOCITY FIELDS
We have applied the Tremaine-Weinberg method to 10 late-type barred spiral galaxies using data cubes, in Hα emission, from the FaNTOmM and GHAFAS Fabry-Perot spectrometers. We have combined theExpand
THE SHEARING H I SPIRAL PATTERN OF NGC 1365
The Tremaine-Weinberg equations are solved for a pattern speed that is allowed to vary with radius. The solution method transforms an integral equation for the pattern speed to a least-squaresExpand

Determination of the Pattern Speed of Barred Spiral Galaxies
We evaluated the availability of a method proposed by Kuno et al. (2000, PASJ, 52, 775) for measuring the pattern speed of barred galaxies, and applied it to observational data. We made errorExpand
