Coronal gas excitation as a tracer of supermassive black hole mass: on the mid-IR coronal [Ne v] lines
J. S. Elford, A. Prieto, A. Rodríguez-Ardila
Coronal lines (CL) may be a reliable proxy of supermassive black hole (SMBH) masses in active galactic nuclei (AGN) because the production of these high ionisation potential (IP) l…
ReveaLLAGN 1: JWST Emission-Line Spectra Reveal Low-Luminosity AGN with UV-Deficient SEDs and Warm Molecular Gas
Kameron Goold, Anil Seth, Mallory Molina +20
We present near- and mid-infrared spectra of eight Low-Luminosity Active Galactic Nuclei (LLAGN), spanning nearly four orders of magnitude in black hole mass and Eddington ratio, o…
Spatially resolved circumnuclear coronal emission in nearby Seyfert galaxies
S. Comerón, A. Prieto, P. Dabhade
Coronal lines are forbidden emission lines with a ionisation potential . They are linked to energetic phenomena triggered by AGNs in the circumnuclear medium…
The size of the Coronal Line Region in Active Galactic Nuclei: a MUSE perspective
A. Rodríguez-Ardila, M. A. Fonseca-Faria, L. G. Dahmer-Hahn +3
We investigated by means of MUSE/VLT observations the true size of the coronal line region (CLR) in a local sample of nine active galactic nuclei known for displaying prominent cor…
Coronal Line Forest AGN I: physical properties of the emission-line regions
F. C. Cerqueira-Campos, A. Rodríguez-Ardila, R. Riffell +3
Coronal-Line Forest Active Galactic Nuclei (CLiF AGN) are characterized by strong high-ionization lines, which contrast to what is found in most AGNs. Here, we carry out a multiwav…
