Manuela Bischetti (INAF OATs), "It's a complicated feedback: linking high-redshift quasar and galaxy growth"
Quantifying quasar feedback is a notoriously difficult task, especially in distant galaxies within the first billion years of cosmic time. I will present a multi-scale and multi-phase view of quasar-driven outflows, traced in both emission and absorption, to investigate how energy is conveyed from galactic cores to the circumgalactic medium. I will discuss strategies to quantify the long-term impact of these outflows on galaxy growth, and address the potentially biased view of enhanced star formation in the most luminous systems. I will present new results on the radio properties of luminous quasars, based on their ubiquitous detection by LOFAR. These data allow us to study statistical samples of traditionally radio-quiet objects at cosmic noon, providing a new independent window into their star formation rates and into the role of the radio-mode feedback channel.
