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…
First detection of outflowing gas in the outskirts of the broad line region in 1H-0707-495
Alberto Rodriguez-Ardila, Marcos Antonio Fonseca-Faria, Denimara Dias dos Santos +2
We use near-infrared (NIR) spectroscopy covering simultaneously the bands to look for outflowing gas from the nuclear environment of 1H0707-495 taking advantage that this re…
Joint analysis of the iron emission in the optical and near-infrared spectrum of I Zw 1
Denimara Dias dos Santos, Swayamtrupta Panda, Alberto Rodríguez-Ardila +1
Constraining the physical conditions of the ionized media in the vicinity of an active supermassive black hole (SMBH) is crucial to understanding how these complex systems operate.…
What drives the Coronal Lines? Resolving the forbidden, high-ionization emission regions in a sample of AGNs
Swayamtrupta Panda, Alberto Rodríguez Ardila, Marcos A. Fonseca Faria +3
Emission-line studies in the active galactic nuclei (AGNs), particularly those utilizing high spatial resolution, provide the most accurate method to determine critical quantities…

Denimara Dias dos Santos, Alberto Rodríguez-Ardila, Swayamtrupta Panda +1
Double-peaked profiles associated with the broad-line region (BLR) of active galactic nuclei (AGNs) are regarded as the clearest evidence of the presence of an accretion disk. They…
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…
Optical Properties of Peaked Spectrum Radio Sources

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…
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…
The CaFe Project: Optical FeII and Near-Infrared Ca II triplet emission in active galaxies. II. The driver(s) of the Ca II and Fe II and its potential use as a chemical clock
Mary Loli Martínez-Aldama, Swayamtrupta Panda, Bożena Czerny +3
In this second paper in the series, we carefully analyze the observational properties of the optical FeII and NIR CaII triplet in Active Galactic Nuclei, as well as the luminosity,…
Faint Quasars Live in the Same Number Density Environments as Lyman Break Galaxies at z ~ 4
