    • AGN candidates in the VVV near-IR galaxy catalogue 

      Baravalle, Laura D.; Schmidt, Eduardo O.; Alonso, M. Victoria; Pichel, Ana; Minniti, Dante; Rodríguez-Kamenetzky, Adriana R.; Masetti, Nicola; Villalon, Carolina; Smith, Leigh C.; Lucas, Philip W. (2023-04-30)
      The goal of this work is to search for Active Galactic Nuclei (AGN) in the Galactic disc at very low latitudes with |b|< 2°. For this, we studied the five sources from the VVV near-infrared (IR) galaxy catalogue that have ...

    • High energy gamma-ray sources in the VVV survey - II. The AGN counterparts 

      Donoso, Laura G; Pichel, Ana; Baravalle, Laura D; Alonso, M Victoria; Schmidt, Eduardo O; Minniti, Dante; Masetti, Nicola; Smith, Leigh C; Lucas, Philip W; Villalon, Carolina; Rovero, Adrián C; Coldwell, Georgina (2024-03-09)
      We identified Active Galactic Nuclei (AGN) candidates as counterparts to unidentified gamma-ray sources (UGS) from the Fermi-LAT Fourth Source Catalogue at lower Galactic latitudes. Our methodology is based on the use of ...

    • VVV-WIT-04: an extragalactic variable source caught by the VVV Survey 

      Saito, Roberto K.; Minniti, Dante; Ivanov, Valentin D.; Masetti, Nicola; Navarro, Maria Gabriela; Fernandes, Roberto Cid; Ruschel-Dutra, Daniel; Smith, Leigh C.; Lucas, Philip W.; Gonzalez-Fernandez, Carlos; Ramos, Rodrigo Contreras (2019-09-20)
      We report the discovery of VVV-WIT-04, a near-infrared (near-IR) variable source towards the Galactic disc located ∼0.2 arcsec apart from the position of the radio source PMN J1515−5559. The object was found serendipitously ...
