Proper motions in the VVV Survey: Results for more than 15 million stars across NGC 6544

Autor: Contreras Ramos, R. Zoccali, M. Rojas, F. Rojas-Arriagada, A. Gárate, M. Huijse, P. Gran, F. Soto, M. Valcarce, A.A.R. Estévez, P.A. Minniti, D.

Context. In the last six years, the VISTA Variable in the Vía Láctea (VVV) survey mapped 562 sq. deg. across the bulge and southern disk of the Galaxy. However, a detailed study of these regions, which includes ∼36 globular clusters (GCs) and thousands of open clusters is by no means an easy chal...

New VVV Survey Globular Cluster Candidates in the Milky Way Bulge

Autor: Minniti, D. Geisler, D. Alonso-Garcia, J. Palma, T. Beamin, J.C. Borissova, J. Catelan, M. Clariá, J.J. Cohen, R.E. Ramos, R.C. Dias, B. Fernández-Trincado, J.G. Gómez, M. Hempel, M. Ivanov, V.D. Kurtev, R. Lucas, P.W. Moni-Bidin, C. Pullen, J. Alegria, S.R. Saito, R.K. Valenti, E.

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 problems for finding globular clusters located toward the bulge. We use the dee...

Gauging the Helium Abundance of the Galactic Bulge RR Lyrae Stars

Autor: Marconi, M. Minniti, D.

We report the first estimate of the He abundance of the population of RR Lyrae stars in the Galactic bulge. This is done by comparing the recent observational data with the latest models. We use the large samples of ab-type RR Lyrae stars found by OGLE IV in the inner bulge and by the VVV survey ...

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...

Comparing the properties of the X-shaped bulges of NGC 4710 and the Milky Way with MUSE

Autor: Gonzalez, O.A. Gadotti, D.A. Debattista, V.P. Rejkuba, M.de Valenti, E. Zoccali, M. Coccato, L. Minniti, D. Ness, M.

Context. Our view of the structure of the Milky Way and, in particular, its bulge is obscured by the intervening stars, dust, and gas in the disc. While great progress in understanding the bulge has been achieved with past and ongoing observations, the comparison of its global chemodynamical prop...

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...
