My PhD research focused on locating and measuring star formation and AGN activity in different environments mainly using interferometric radio continuum observations. As my first project, I studied the complex interaction between an intermediate redshift (z ~ 0.3) starburst galaxy and a nearby (~ 7 kpc separation) AGN using new, sub-arcsecond VLA observations. I found new evidence for jet-induced star formation activity in the companion starburst, making the system a strong candidate for this rare, and potentially important process in the early Universe. In my second paper, I investigated the infrared-radio correlation (IRRC) of spheroid- and disc-dominated galaxies out to z ~ 1.5, and found different redshift dependent trends for these systems. Finally, I will present early results from my on-going effort to compile the largest-to-date low-z IRRC sample, that ultimately aims to pave the way for new generation radio star formation surveys with SKA and its precursor facilities, MeerKAT and ASKAP.
