Unveiling the quasar main sequence: illuminating the complexity of active galactic nuclei and their evolution
Published in Frontiers in Astronomy and Space Sciences
The Eigenvector 1 schema, or the main sequence of quasars, was introduced as an analogous scheme to the HR diagram that would allow us to understand the more complex, extended sources - active galactic nuclei (AGNs) that harbor accreting supermassive black holes. The study has spanned more than three decades and has advanced our knowledge of the di...
