VVV Survey Microlensing Events in the Galactic Center Region
María Gabriela Navarro, Dante Minniti, Rodrigo Contreras Ramos
We search for microlensing events in the highly reddened areas surrounding the Galactic center using the near-IR observations with the VISTA Variables in the Vía Láctea Survey (VVV…
Searching for Extragalactic Sources in the VISTA Variables in the Vía Láctea Survey
Laura D. Baravalle, M. Victoria Alonso, José L. Nilo Castellón +2
We search for extragalactic sources in the VISTA Variables in the Vía Láctea survey that are hidden by the Galaxy. Herein, we describe our photometric procedure to find and charact…
Disentangling the Galactic Halo with APOGEE: I. Chemical and Kinematical Investigation of Distinct Metal-Poor Populations
Christian R. Hayes, Steven R. Majewski, Matthew Shetrone +21
We find two chemically distinct populations separated relatively cleanly in the [Fe/H] - [Mg/Fe] plane, but also distinguished in other chemical planes, among metal-poor stars (pri…
Duality transformation and conformal equivalent scalar-tensor theories
Gabriele Gionti, S. J., Andronikos Paliathanasis
We deal with the duality symmetry of the Dilaton field in cosmology and specifically with the so-called Gasperini-Veneziano duality transformation. In particular, we determine two…
VIRAC: The VVV Infrared Astrometric Catalogue
L. C. Smith, P. W. Lucas, R. Kurtev +12
We present VIRAC version 1, a near-infrared proper motion and parallax catalogue of the VISTA VVV survey for 312,587,642 unique sources averaged across all overlapping pawprint and…
Extinction ratios in the inner Galaxy as revealed by the VVV survey
Javier Alonso-García, Dante Minniti, Márcio Catelan +7
Interstellar extinction towards the Galactic Center is large and significantly differential. Its reddening and dimming effects in red clump stars in the Galactic Bulge can be explo…
