This regulation process is known as \u2018feedback\u2019 and suggests that the relatively small black hole can influence the rate that the much larger galaxy forms stars. One of the prime mechanisms for this feedback are the powerful bipolar jets often emitted by black holes which produce bright radio emission.<\/p>\n\n\n\n<p class=\"has-intro-font-size wp-block-paragraph\">Aim&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Large multi-wavelength surveys provide a census of both jet power from the radio emission and the on-going star formation rates (SFRs) from the UV\/optical\/IR data in millions of sources. This project will leverage a consistent approach to measuring the star formation rates from modelling the UV\/optical\/IR to then compare to jet power and apply to a numerous state of the art surveys. The aim of this project will be to quantify how jet power varies with the host galaxy properties (SFR, stellar mass, star formation history, environment) and cosmic time.<\/p>\n\n\n\n<p class=\"has-intro-font-size wp-block-paragraph\">Objectives&nbsp;<\/p>\n\n\n\n<ol style=\"list-style-type:lower-alpha\" class=\"wp-block-list\">\n<li>Collate the latest radio data from numerous multi-wavelength surveys to identify those sources powered by radio jets.<\/li>\n\n\n\n<li>Search for correlation between the radio jet luminosity and the host galaxies\u2019 properties over different epochs.<\/li>\n\n\n\n<li>Model the radio emission to obtain the jet power and age of the jet to compare to star formation history.<\/li>\n\n\n\n<li>Obtain follow-up data from ground and space based telescopes of the most promising candidates to catch the feedback process in action.<\/li>\n<\/ol>\n\n\n\n<p class=\"has-intro-font-size wp-block-paragraph\">Significance&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The process of feedback is a critical, but not well understood component of galaxy evolution. This project will be the first to self-consistently analyse numerous multi-wavelength surveys. It will support one of the key science goals of the SKA &#8211; tracing the evolution of galaxies over cosmic time.<\/p>\n\n\n\n<p class=\"has-intro-font-size wp-block-paragraph\">Ideal Candidate&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We are looking for a self-motivated PhD candidate with a background in physics, astronomy or computing\/data science.
