    • Characterization of the VVV Survey RR Lyrae Population across the Southern Galactic Plane 

      Minniti, Dante; Dékány, Istvan; Majaess, Daniel; Palma, Tali; Pullen, Joyce; Rejkuba, Marina; Alonso-García, Javier; Catelan, Marcio; Ramos, Rodrigo Contreras; Gonzalez, Oscar A.; Hempel, Maren; Irwin, Mike; Lucas, Philip W.; Saito, Roberto K.; Tissera, Patricia; Valenti, Elena; Zoccali, Manuela (2017-03-27)
      Deep near-IR images from the VISTA Variables in the Vía Láctea (VVV) Survey were used to search for RR Lyrae stars in the Southern Galactic plane. A sizable sample of 404 RR Lyrae of type ab stars was identified across a ...

    • The Emergence of the Infrared transient VVV-WIT-06 

      Minniti, Dante; Saito, Roberto K.; Forster, F.; Pignata, G.; Ivanov, Valentin D.; Lucas, Philip; Beamin, J.C.; Borissova, Jura; Catelan, Marcio; Gonzalez, Oscar A.; Hempel, Maren; Hsiao, E; Kurtev, Radostin; Majaess, Daniel; Masetti, N.; Morrell, N.I.; Phillips, M.M.; Pullen, J. B.; Rejkuba, M.; Smith, L.C.; Surot, F.; Valenti, Elena; Zoccali, Manuela (2017-11-03)
      We report the discovery of an enigmatic large-amplitude (ΔKs> 10.5 mag) transient event in near-IR data obtained by the VISTA Variables in the Via Lactea (VVV) ESO Public Survey. The object (designated VVV-WIT-06) is located ...

    • 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 ...

    • New VVV Survey Globular Cluster Candidates in the Milky Way Bulge 

      Minniti, Dante; Geisler, Douglas; Alonso-García, Javier; Palma, Tali; Beamin, Juan Carlos; Borissova, Jura; Catelan, Marcio; Clariá, Juan J.; Cohen, Roger E.; Ramos, Rodrigo Contreras; Dias, Bruno; Fernandez-Trincado, Jose; Gomez, Matias; Hempel, Maren; Ivanov, Valentin D.; Kurtev, Radostin; Lucas, Philip; Moni-Bidin, Christian; Pullen, Joyce; Alegría, Sebastian Ramírez; Saito, Roberto K.; Valenti, Elena (2017-11-10)
      It is likely that a number of Galactic globular clusters remain to be discovered, especially toward the Galactic bulge. High stellar density combined with high and differential interstellar reddening are the two major ...
