Galaxy Dynamics, Star Formation and footsteps to WALLABY and MHONGOOSE-- Moses Mogotsi Colloquium

Marsfield Lecture Theatre

Abstract

The dynamics of galaxies can either inhibit or allow star
formation; and when star formation occurs it can self-regulate via
feedback processes and this will affect the dynamics of the gas and host
galaxy. So, galaxy dynamics on both small-scales and large scales are
tied to star formation. Studying gas kinematics via spectral line
observations is very useful in this regard. The main part of the talk
will be about studying the links between star formation and gas kinematics
in nearby galaxies using optical and radio spectral line surveys and other
multi-wavelength data. I will discuss my current work on the H-alpha
kinematics and star formation of nearby HI-selected star forming galaxies
that are part of the SINGG-SUNGG survey, and how this work will contribute
to the MHONGOOSE and WALLABY HI surveys with MeerKAT and ASKAP. I will
also talk about my velocity dispersion study of the THINGS, HERACLES and
SINGS-Halpha surveys.
