AGN Physics and Future Spectroscopic Surveys
Analysis
Key Takeaways
- •The paper focuses on connecting accretion disk and X-ray corona physics with nebular regions and CGM.
- •It emphasizes the importance of the Lx-Luv relation and deviations from it.
- •The study proposes using emission lines and CGM nebulae to probe the ionizing SED.
- •It outlines observational strategies including UV/optical spectroscopy, time-domain reverberation mapping, X-ray coverage, and IFU mapping.
- •The paper derives requirements for a future ESO facility in the 2040s: a wide-field, high-multiplex spectroscopic telescope with time-domain and IFU capabilities.
“The paper proposes to use broad and narrow line emission and CGM nebulae as calorimeters of the ionising SED to trace different accretion "states".”
