Description
The interplay between gas accretion, feedback, and galactic dynamics plays a crucial role in shaping galaxy evolution. The MHONGOOSE survey, with its unprecedented HI sensitivity and high spatial resolution, provides a transformative opportunity to study these complex processes in nearby galaxies. By probing gas at extremely low column densities in the outskirts of galaxies, MHONGOOSE enables the detection and characterization of gas kinematics in regimes previously inaccessible. In this talk, I will discuss the kinematic properties observed across the diverse MHONGOOSE galaxy sample, ranging from systems with well-ordered kinematics to those exhibiting complex, disturbed dynamics, particularly evident at large radii and low gas column densities. Using high-quality rotation curves derived from 3D tilted ring modeling, I will discuss how this kinematic diversity can be quantified and investigate the potential origins of such diversity, including the roles of gas accretion, interactions, and internal processes.
