The Impact of Bar-induced Noncircular Motions on the Measurement of Galactic Rotation Curves

The Astrophysical Journal
We study the impact of bar-induced noncircular motions on the derivation of galactic rotation curves (RCs) using hydrodynamic simulations and observational data from the PHANGS-ALMA survey.

GBT/Argus Observations of Molecular Gas in the Inner Regions of IC 342

The Astrophysical Journal
We report observations of the ground state transitions of ^12 CO, ^13 CO, C ^18 O, HCN, and HCO ^+ at 88–115 GHz in the inner region of the nearby galaxy IC 342.

The TYPHOON Stellar Population Synthesis Survey. II. Pushing Full Spectral Fitting to the Limit in the Nearby Grand Design Barred Spiral M83

The Astrophysical Journal
We apply population synthesis techniques to analyze TYPHOON long slit spectra of the starburst barred spiral galaxy M83. The analysis covers a central square of 5′ side length.

Comparison of Bar Formation Mechanisms. I. Does a Tidally Induced Bar Rotate Slower than an Internally Induced Bar?

The Astrophysical Journal
Galactic bars can form via the internal bar instability or external tidal perturbations by other galaxies. We systematically compare the properties of the bars formed through the two mechanisms with a series of controlled N -body simulations that form ...
