Kinematics of molecular gas in star-forming galaxies with large-scale ionized outflows

We investigate the kinematics of molecular gas in a sample seven edge-on (i>60{\deg}) galaxies identified as hosting large-scale outflows ionised gas, using ALMA CO(1-0) observations at ~ 1kpc resolution. build on Hogarth et al. (2021; H21), where we find that is more centrally concentrated which host winds than control objects. perform full 3-dimensional kinematic modelling with multiple combinations components, allowing us to infer whether these objects share any similarities their structure. use pinpoint centre each galaxy, order interpret minor- and major-axis position velocity diagrams (PVDs). From PVDs, bulk our dynamically cold, tracing rotation curves predicted by symmetric, rotation-dominated models, but minor flux asymmetries. Most notably, evidence radial motion subset objects, demonstrate characteristic "twisting" minor-axis PVDs generally associated flow along plane galaxy. In highest S/N object, include bi-symmetric model, (via Bayesian Information Criterion) presence strongly favoured. This may provide one mechanism star formation are concentrated, enabling launch massive winds. However, remainder sample, do not observe being driven radially, once again emphasising variety physical processes be powering originally noted H21.
