    • Discovery of new globular clusters in the Sagittarius dwarf galaxy 

      Minniti, D.; Ripepi, V.; Fernández-Trincado, J. G.; Alonso-García, J.; Smith, L. C.; Lucas, P. W.; Gómez, M.; Pullen, J. B.; Garro, E. R.; Cádiz, F. Vivanco; Hempel, M.; Rejkuba, M.; Saito, R. K.; Palma, T.; Clariá, J. J.; Gregg, M.; Majaess, D. (2021-03-12)
      Context. Globular clusters (GCs) are witnesses of the past accretion events onto the Milky Way. In particular, the GCs of the Sagittarius (Sgr) dwarf galaxy are important probes of an on-going merger. Aims. Our main goal ...

    • 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 ...

    • Searching for Faint Comoving Companions to the α Centauri system in the VVV Survey Infrared Images 

      Beamin, J.C.; Minniti, D.; Pullen, J. B.; Ivanov, Valentin D.; Bendek, E.; Bayo, A.; Gromadzki, M.; Kurtev, R.; Lucas, P. W.; Butler, R. P. (2017-12-21)
      The VVV survey has observed the southern disk of the Milky Way in the near infrared, covering 240 deg$^{2}$ in the $ZYJHK_S$ filters. We search the VVV Survey images in a $\sim$19 deg$^{2}$ field around $\alpha$ Centauri, ...

    • VVVX-Gaia Discovery of a Low Luminosity Globular Cluster in the Milky Way Disk 

      Garro, E. R.; Minniti, D.; Gómez, M.; Alonso-García, J.; Barbá, R. H.; Barbuy, B.; Clariá, J. J.; Chené, A. N.; Dias, B.; Hempel, M.; Ivanov, V. D.; Lucas, P. W.; Majaess, D.; Mauro, F.; Bidin, C. Moni; Palma, T.; Pullen, J. B.; Saito, R. K.; Smith, L.; Surot, F.; Alegría, S. Ramírez; Rejkuba, M.; Ripepi, V. (2020-10-22)
      Milky Way globular clusters (MW GCs) are difficult to identify at low Galactic latitudes because of high differential extinction and heavy star crowding. The new deep near-IR images and photometry from the VISTA Variables ...
