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…

Euclid: Measuring the intrinsic alignment of galaxies around cosmic voids in the \Euclid Flagship simulation\
P. Vielzeuf, M. -C. Cousinou, A. Pisani +149
We present a methodology to measure the intrinsic alignment (IA) signal of galaxies in the vicinity of cosmic voids using the \Euclid-like Flagship cosmological simulation from the…

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…
