Seminario de Física Teórica: "Of Monsters and Jets: Exploring Active Galactic Nuclei across wavelengths and scales".- Martes 10 de febrero
El martes 10 de febrero de 2026 a las 16:10 h se celebrará un nuevo seminario organizado por el Departamento de Física Teórica, con el título "Of Monsters and Jets: Exploring Active Galactic Nuclei across wavelengths and scales" e impartido por David Fernández Gil (Centro de Estudios de Física del Cosmos de Aragón). Tendrá lugar en el Seminario de Física Atómica, Molecular y Nuclear, ubicado en la planta calle del edificio A.
Resumen (en inglés):
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.
