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…
Simultaneous modeling of FeII emission in the optical and near-infrared in a prototypical Narrow-Line Seyfert 1 galaxy
Denimara Dias dos Santos, Swayamtrupta Panda, Alberto Rodríguez-Ardila +1
This work investigates the FeII emission in active galactic nuclei (AGN), combining observational data from optical and near-infrared (NIR) spectra of the prototypical FeII emitter…
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 -- II. Analysis of the spectral energy distribution
F. C. Cerqueira-Campos, A. Rodríguez-Ardila, S. Panda +3
Coronal-Line Forest Active Galactic Nuclei (CLiF AGN) are characterized by strong, high-ionization lines, which are in contrast to what is found in typical AGNs. Here, we carry out…
Physical Conditions and Extension of the Coronal Line Region in IC 5063
M. A. Fonseca-Faria, A. Rodríguez-Ardila, M. Contini +2
We study the ionised and highly ionised gas phases in the Seyfert~2 galaxy IC~5063 by means of VLT/MUSE integral field spectroscopy. Our analysis allowed us to detect a high-ionisa…
A Decade of Near-Infrared Variability in NGC4388: Insights into the AGN Structure
Luis G. Dahmer-Hahn, Alberto Rodríguez-Ardila, Marina Bianchin +4
Variability studies have proven to be a powerful diagnostic tool for understanding the physics and properties of of Active Galactic Nuclei (AGNs). They provide insights into the sp…
A closer look at NGC 7314 nuclear region: a multiwavelength analysis of the Seyfert nucleus and its surroundings
Patrícia da Silva, R. B. Menezes, Y. Díaz +4
The central regions of galaxies harbouring active galactic nuclei (AGNs) can be quite complex, especially at high activity, presenting, besides variability, a variety of phenomena…
Warm molecular and ionized gas kinematics in the Type-2 quasar J0945+1737
G. Speranza, C. Ramos Almeida, J. A. Acosta-Pulido +11
We analyze Near-Infrared Integral Field Spectrograph (NIFS) observations of the type-2 quasar (QSO2) SDSS J094521.33+173753.2 to investigate its warm molecular and ionized gas kine…
Optical Properties of Peaked Spectrum Radio Sources
R. S. Nascimento, A. Rodríguez-Ardila, L. Dahmer-Hahn +5
In this work, we study the optical properties of compact radio sources selected from the literature in order to determine the impact of the radio-jet in their circumnuclear environ…
A novel black-hole mass scaling relation based on coronal gas, and its dependence with the accretion disc
M. Almudena Prieto, Alberto Rodríguez-Ardila, Swayamtrupta Panda +1
Using bona-fide black hole (BH) mass estimates from reverberation mapping and the line ratio [SiVI] 1.963m/Br as tracer of the AGN ionising continuum, a novel BH-…
Stellar populations in local AGNs: evidence for enhanced star formation in the inner 100pc
L. G. Dahmer-Hahn, R. Riffel, A. Rodríguez-Ardila +7
In modern models and simulations of galactic evolution, the star formation in massive galaxies is regulated by an ad hoc active galactic nuclei (AGN) feedback process. However, the…
