Radio galaxies and galaxy evolution
It is now widely recognised that radio jets powered by supermassive black holes can play a critical role in galaxy evolution by regulating the star-formation rate within their host galaxies. This talk will cover two distinct (but related) topics: radio galaxies and galaxy evolution.
I will first discuss the cosmic evolution of several different populations of radio AGN (including QSOs) over the redshift range 0 < z < 1, based on a new radio study of three fields from the GAMA galaxy survey. The second part of the talk will focus on the role of neutral gas in galaxy evolution, and the effects of AGN fuelling and feedback. Here, I will present some of the first ASKAP detections of redshifted 21cm HI absorption in the redshift range 0.4 < z < 1, and discuss what these kinds of measurements can tell us (now and in the future) about the amount and distribution of neutral hydrogen in individual galaxies in the distant Universe.
