Spiral Density Waves in the Multiple-armed Galaxy NGC 628

The Astrophysical Journal
Radial profiles of pattern speeds are measured at subkiloparsec resolution for NGC 628. The radial profiles are directly measured using a general form of the Tremaine–Weinberg method that allows for the pattern speed to vary with radius.

The Impact of Shear on Disk Galaxy Star Formation Rates

The Astrophysical Journal Letters
Determining the physical processes that control galactic-scale star formation rates is essential for an improved understanding of galaxy evolution. The role of orbital shear is currently unclear, with some models expecting reduced star formation rates ...
