"Of Monsters and Jets: Exploring Active Galactic Nuclei across wavelengths and scales"

Abstract:

Active Galactic Nuclei (AGN) are cosmic engines shaping the evolution of their galactic hosts. In this talk, I will explore how AGN, their relativistic jets, 
and their host galaxies are interconnected across vastly different scales and wavelengths. I will present results from observations of the parsec-scale, 
innermost region of the jets, revealing a surprising statistical alignment with the structure of the host galaxy, despite a difference in size of 4 orders 
of magnitude. Next, I will explain how by combining narrow-band optical, low-frequency radio, and infrared observations, we can get access to a 
multi-wavelength window into AGN activity and feedback. We see that galaxies with extended radio jets show signs of quenched star formation. 
Finally, I will discuss future plans of studying the life-cycle of AGN and their jets, highlighting how the lifetimes and evolution of jets may regulate star 
formation and influence galaxy evolution over cosmic timescales.
