    • The excitation mechanisms and evolutionary stages of UWISH2 planetary nebula candidates 

      Jones, Alex; Gledhill, Timothy; Froebrich, Dirk; Smith, Michael (2018-10-01)
      We present medium-resolution K-band long-slit spectroscopy of 29 true, likely, possible, and candidate Galactic Plane planetary nebulae (PNe) from the UWISH 2 survey, many of which have only been recently discovered. These ...
    • FSR 1716: A new Milky Way Globular Cluster confirmed using VVV RR Lyrae stars 

      Minniti, Dante; Palma, Tali; Dékány, Istvan; Hempel, Maren; Rejkuba, Marina; Pullen, Joyce; Alonso-García, Javier; Barbá, Rodolfo; Barbuy, Beatriz; Bica, Eduardo; Bonatto, Charles; Borissova, Jura; Catelan, Marcio; Carballo-Bello, Julio A.; Chene, Andre Nicolas; Clariá, Juan J.; Cohen, Roger E.; Contreras-Ramos, Rodrigo; Dias, Bruno; Emerson, Jim; Froebrich, Dirk; Buckner, Anne S. M.; Geisler, Douglas; Gonzalez, Oscar A.; Gran, Felipe; Hagdu, Gergely; Irwin, Mike; Ivanov, Valentin D.; Kurtev, Radostin; Lucas, Philip W.; Majaess, Daniel; Mauro, Francesco; Moni-Bidin, Christian; Navarrete, Camila; Alegría, Sebastian Ramírez; Saito, Roberto K.; Valenti, Elena; Zoccali, Manuela (2017-03-24)
      We use deep multi-epoch near-IR images of the VISTA Variables in the V\'ia L\'actea (VVV) Survey to search for RR Lyrae stars towards the Southern Galactic plane. Here we report the discovery of a group of RR Lyrae stars ...
    • Photometric variability of massive young stellar objects 

      Teixeira, G. D. C.; Kumar, M. S. N.; Smith, L.; Lucas, P. W.; Morris, C.; Borissova, J.; Monteiro, M. J. P. F. G.; Garatti, A. Caratti o; Peña, C. Contreras; Froebrich, Dirk; Gameiro, J. F. (2018-11-05)
      The Vista Variables in the Via Lactea (VVV) survey has allowed for an unprecedented number of multi-epoch observations of the southern Galactic plane. In a recent paper, 13 massive young stellar objects (MYSOs) have already ...
    • Planetary Nebulae in the UWISH2 survey 

      Gledhill, Timothy; Froebrich, Dirk; Campbell-White, J.; Jones, Alex (2018-09-21)
      Near-infrared imaging in the 1 - 0 S(1) emission line of molecular hydrogen is able to detect planetary nebulae (PNe) that are hidden from optical emission line surveys.We present images of 307 objects from the UWISH2 ...
