Multi-tracer constraints on quasar outflows. Acceleration from BLR to galactic scales
M. Brazzini, M. Bischetti, S. Hagen +14
Black hole-driven outflows are a fundamental component of the Active Galactic Nuclei (AGN) paradigm, and may play a major role in regulating the evolution of both supermassive blac…
Physically motivated AGN emissivity profiles and their effects on quasar microlensing signatures. 1. Multi-epoch accretion disc size inference
Scott Hagen, Carina Fian
Quasar microlensing is uniquely sensitive to the size-scale of the accretion flow, offering one of the few direct probes of the accretion structure on micro-arcsecond scales. Howev…
Understanding the Broad-line Region of Active Galactic Nuclei with Photoionization. II. Slim disks, Self-shadowing, and BLR sizes
Qiaoya Wu, Yue Shen, Chris Done +2
Reverberation-mapping (RM) measurements have revealed that high-accretion-rate active galactic nuclei (AGNs) systematically lie below the canonical broad-line region (BLR) radius -…
Unveiling BLR Structure in AGN with High Resolution X-Ray Spectra: An Analytic Approach to Wind Emission Line Profiles
Scott Hagen, Chris Done, Gabriele A. Matzeu +1
XRISM has provided an unprecedented view of the emission and absorption lines in the X-ray. Notably, early results showed significant complexity to the Fe-K line profile in AGN,…
