The Research Project

Many galaxy properties, including mass, star formation history and morphology, are correlated with their environments. The properties of Active Galactic Nuclei (AGN) hosted by these galaxies are similarly sensitive to where the galaxy finds itself. For example, powerful radio AGN, produced by relativistic jet launching by a combination of spin and accretion onto a supermassive black hole, are found overwhelmingly in galaxy groups and clusters. Interpreting the observable properties of radio AGN is important for quantifying the amount of feedback these objects do on their host galaxies and beyond, yet this too depends on knowledge of the environment into which the jets are propagating.

GAMA Legacy ATCA Southern Survey (GLASS) is a 3000-hour Legacy survey on the Australia Telescope Compact Array (ATCA), Australia's premier radio astronomy instrument. GLASS conducts sensitive observations of 50 square degrees of the sky at 5.5 and 9.5 GHz. A key feature of GLASS is availability of environment measures through deep optical group catalogues covering the survey field. The two main science goals are to measure the demographics of Active Galactic Nuclei and star forming galaxies in both the nearby and high-redshift Universe, as a function of environment.

This PhD project will focus on imaging GLASS data, and constructing catalogues of radio sources and their host galaxies across a wide range of radio, optical and infra-red wavelengths, for a complete census of AGN, star forming galaxies, and their environments. For an interested student, an AGN modeling component using the UTAS-developed RAiSE dynamical model is also a possibility. This project will be performed in collaboration with colleagues CSIRO Astronomy and Space Science.
