Astrophysicist at Swinburne University of Technology

I’m Sarah Sweet, an Astrophysicist at the Swinburne University of Technlology.

I study galaxy formation and evolution.

I'm interested in the formation and evolution of galaxies of various sizes across different environments and redshifts. I investigate the metallicities and kinematics of star-forming galaxies with multi-object and integral field spectroscopy. I use high-resolution adaptive optics imaging to trace the evolution of galaxies in over cosmic time.

    Choirs, HI Galaxy Groups

    Choirs

    Choirs are a type of gas-rich galaxy group, found in the Survey for Ionization in Neutral Gas Galaxies, that contain multiple star-forming galaxies.

    Dwarf Galaxy Metallicity

    Luminosity-Metallicity Relation

    Dwarf galaxies that form in tidal interactions between metal-rich giants are themselves metal-rich. I present the luminosity-metallicity relation as a diagnostic for their idenfication.

    Dwarf Galaxy Kinematics

    Kinematics

    Can dwarf galaxies that form in tidal interactions survive and be detected by their kinematics?
