XRISM Resolves the Circum-nuclear Environment of NGC 4945
Peter G. Boorman, Poshak Gandhi, Yoshihiro Ueda +31
Compton-thick Active Galactic Nuclei (AGN) represent one of the most elusive phases of massive black hole growth, yet are expected to contribute substantially to the Cosmic X-ray B…

Extreme Variability Reveals How the Eddington Ratio Regulates Coronal Power in Active Galactic Nuclei
Arghajit Jana, Claudio Ricci, Franz E. Bauer +13
The bolometric luminosity () of active galactic nuclei (AGNs) is a key tracer of accretion physics, but its direct determination is often hindered by limited spectral…

The study of the circumnuclear environment of accreting supermassive black holes with realistic X-ray spectral models
Georgios Dimopoulos, Claudio Ricci, Stéphane Paltani
X-ray spectral modeling is a powerful tool for studying the immediate environment of accreting objects, including supermassive black holes. Several models, either phenomenological…
