The co-evolution of central supermassive black holes (SMBH) and their host galaxies is now well-established both in theory and observations. On the other hand, observational evidence for the enhancement or suppression of star formation due to accreting central supermassive black holes (also known as Active Galactic Nuclei, AGN) is still an open question even though current theoretical simulations suggest that star formation within a galaxy is suppressed and regulated via a “radio maintenance” mode whereby the hot magnetised plasma, traced by the AGN powered radio emission, is driving the cool gas out of galaxies.

The purpose of this project is to correlate the different morphologies of radio AGN emission as identified through Radio Galaxy Zoo(RGZ) project to the morphologies and star formation properties of the host galaxies from the Galaxy Zoo (GZ) project. The student will produce several catalogues of RGZ +GZ cross-identifications for different classes of objects. For the low-redshift radio sources (z<0.2), the student will also compare the radio morphologies as a function of optical spectroscopic galaxy properties (such as emission line ratio diagnostics).
