Autor: Minniti, D. Dékány, I. Majaess, D. Palma, T. Pullen, J. Rejkuba, M. Alonso-García, J. Catelan, M. Contreras Ramos, R. Gonzalez, O.A. Hempel, M. Irwin, M.l Lucas, P.W. Saito, R.K. Tissera, P. Valenti, E. Zoccali, M.

Deep near-IR images from the VISTA Variables in the Via Lactea (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 thin slice of the fourth Galactic quadrant (295 degrees < l < 350 degrees, -...

Structure and kinematics of Type II Cepheids in the Galactic bulge based on near-infrared VVV data

Autor: Braga, V.F. Bhardwaj, A. Contreras Ramos, R. Minniti, D. Bono, G. De Grijs, R. Minniti, J.H. Rejkuba, M.

Context. Type II Cepheids (T2Cs) are radially pulsating variables that trace old stellar populations and provide distance estimates through their period-luminosity (PL) relation. Aims. We trace the structure of old stellar population in the Galactic bulge using new distance estimates and kinemati...

VVV Survey Microlensing Events in the Galactic Center Region

Autor: Navarro, M.G. Minniti, D. Ramos, R.C.

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). We report the discovery of 182 new microlensing events, based on observations acquired between 2010 and 2015. We p...

Mapping the outer bulge with RRab stars from the VVV Survey

Autor: Gran, F. Minniti, D. Saito, R. K. Zoccali, M. Gonzalez, O. A. Navarrete, C. Catelan, M. Contreras Ramos, R. Elorrieta, F. Eyheramendy, S. Jordán, A.

Context. The VISTA Variables in the Vía Láctea (VVV) is a near-IR time-domain survey of the Galactic bulge and southern plane. One of the main goals of this survey is to reveal the 3D structure of the Milky Way through their variable stars. In particular, enormous numbers of RR Lyrae stars have b...

Stellar density profile and mass of the Milky Way bulge from VVV data

Autor: Valenti, E. Zoccali, M. Gonzalez, O. A. Minniti, D. Alonso-García, J. Marchetti, E. Hempel, M. Renzini, A. Rejkuba, M.

We present the first stellar density profile of the Milky Way bulge that reaches latitude b = 0 degrees. The profile was derived by counting red clump stars within the colour-magnitude diagram that was constructed using the new PSF-fitting photometry from VISTA Variables in the Via Lactea (VVV) s...
