Near-infrared emission line diagnostics for AGN from the local Universe to z ~ 3 [PDF]
Astronomy & Astrophysics, 2023 Optical rest-frame spectroscopic diagnostics are usually employed to distinguish between star formation and AGN-powered emission. However, this method is biased against dusty sources, hampering a complete census of the AGN population across cosmic epochs.

General relativistic effects and the near-infrared and X-ray variability of Sgr A* I [PDF]
Astronomy & Astrophysics, 2023 The near-infrared (NIR) and X-ray emission of Sagittarius A* shows occasional bright flares that are assumed to originate from the innermost region of the accretion flow. We identified $25$ $4.5 \mu m$ and $24$ X-ray flares in archival data obtained with
