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

open access: yesThe 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

open access: yesThe 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.

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

open access: yesThe 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 ...
