    • Coronal-line forest active galactic nuclei I. Physical properties of the emission-line regions 

      Campos, Fernando Custodio Cerqueira; Rodriguez-Ardila, Alberto; Riffel, Rogério; Oliveira, Murilo Marinello Assis de; Allende Prieto, Carlos; Hahn, Luis Gabriel Dahmer (2021) [Artigo de periódico]
      Coronal-line forest (CLiF) active galactic nuclei (AGNs) are characterized by strong high-ionization lines, which contrasts with what is found in most AGNs. Here, we carry out a multiwavelength analysis aimed at understanding ...

    • Coronal line forest AGN : II. Analysis of the spectral energy distribution 

      Campos, Fernando Custodio Cerqueira; Rodriguez-Ardila, Alberto; Panda, Swayamtrupta; Riffel, Rogério; Hahn, Luis Gabriel Dahmer; Oliveira, Murilo Marinello Assis de (2023) [Artigo de periódico]
      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 an infrared analysis aimed at understanding ...

    • Optical properties of Peaked Spectrum radio sources 

      Nascimento, Raquel Santiago; Rodriguez-Ardila, Alberto; Hahn, Luis Gabriel Dahmer; Faria, Marcos Antonio Fonseca; Riffel, Rogério; Oliveira, Murilo Marinello Assis de; Beuchert, Tobias; Callingham, Joseph (2022) [Artigo de periódico]
      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 environment. Our sample includes 58 Compact Steep ...

    • Stellar populations in local AGNs : evidence for enhanced star formation in the inner 100 pc 

      Hahn, Luis Gabriel Dahmer; Riffel, Rogério; Rodriguez-Ardila, Alberto; Riffel, Rogemar André; Storchi-Bergmann, Thaisa; Oliveira, Murilo Marinello Assis de; Davies, Richard I.; Burtscher, Leonard; Dutra, Daniel Ruschel; Rosario, David (2022) [Artigo de periódico]
      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 physics and the extension of such effects ...
