Colloquium - A low-frequency radio perspective on AGN

Submitter: Leah Morabito
Description: Almost every massive galaxy is believed to have a super-massive black hole in its centre, and there is clear evidence this can influence a galaxy’s evolutionary path. These super-massive black holes are a small fraction of a galaxy’s overall mass, yet there are tight correlations between the mass of the black hole and general properties (e.g., mass) of the galaxy. The physical processes which govern the co-evolution of the super-massive black holes and their host galaxies are still unknown, but advances in low frequency radio astronomy can offer new insights. I will present several ways which low frequency observations can help advance our understanding of this co-evolution, which will include studies of individual objects as well as surveys, and give an outlook for the future of low-frequency radio astronomy. In particular I will focus on high resolution imaging at low frequencies, and how the Low Frequency Array can be used to make the first high-resolution, wide area survey.
