Exploring the thickness of galaxy disks in HI

Understanding the thicknesses of disk galaxies is crucial since it allows the determination of galaxy properties such as the volumetric star formation law and the shape of dark matter halo. The HI component stands out since neutral hydrogen due to its ubiquity in disk galaxies and its tight connection to star formation and feedback in galaxies.  In this project, we will present the results obtained from examining the HI scale heights of four edge-on MHONGOOSE galaxies at z = 0, discuss how they relate to other properties of the galaxies, including the scale height in the IR and optical, and discuss the implications for star formation and feedback in these galaxies.
