C.Babusiaux, C.Gilmore, G.Randich, S.Alfaro, E.C., Allende PrietoBragaglia, A.Carraro, G.Jofré, P.Lardo, C.Monaco, L.Morbidelli, L.Zaggia, S.[The Gaia-ESO Survey: Low-α element stars in the Galactic bulge]The Gaia-ESO Survey: Low-α element stars in the Galactic bulge

Context. The globular cluster HP 1 is projected at only 3.̊33 from the Galactic center. Together with its distance, this makes it one of the most central globular clusters in the Milky Way. It has a blue horizontal branch (BHB) and a metallicity of [Fe/H] ≈ −1.0. This means that it probably is on...


Barbuy, B.Cantelli, E.Vemado, A.Ernandes, H.Ortolani, S.Saviane, I.Bica, E.Minniti, D.Dias, B.Momany, Y.Hill, V.Zoccali, M.Siqueira-Mello, C.[High-resolution abundance analysis of red giants in the metal-poor bulge globular cluster HP 1]High-resolution abundance analysis of red giants in the metal-poor bulge globular cluster HP 1

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...


Gonzalez, O. A.Gadotti, D. A.Debattista, V. P.Rejkuba, M.Valenti, E.Zoccali, M.Coccato, L.Minniti, D.Ness, M.[Comparing the properties of the X-shaped bulges of NGC 4710 and the Milky Way with MUSE]Comparing the properties of the X-shaped bulges of NGC 4710 and the Milky Way with MUSE

Context. The inner regions of the Galaxy are severely affected by extinction, which limits our capability to study the stellar populations present there. The Vista Variables in the Vía Láctea (VVV) ESO Public Survey has observed this zone at near-infrared wavelengths where reddening is highly dim...


Alonso-García, J.Saito, R.K.Hempel, M.Minniti, D.Pullen, J.Catelan, M.Ramos, R.C.Cross, N.J.G.Gonzalez, O.A.Lucas, P.W.Palma, T.Valenti, E.Zoccali, M.[Milky Way demographics with the VVV survey: IV. PSF photometry from almost one billion stars in the Galactic bulge and adjacent southern disk]Milky Way demographics with the VVV survey: IV. PSF photometry from almost one billion stars in the Galactic bulge and adjacent southern disk

Context. Oxygen and zinc in the Galactic bulge are key elements for the understanding of the bulge chemical evolution. Oxygen-to-iron abundance ratios provide a most robust indicator of the star formation rate and chemical evolution of the bulge. Zinc is enhanced in metal-poor stars, behaving as ...


Da Silveira, C.R.Barbuy, B.Friaça, A.C.S.Hill, V.Zoccali, M.Rafelski, M.Gonzalez, O.A.Minniti, D.Renzini, A.Ortolani, S.[Oxygen and zinc abundances in 417 Galactic bulge red giants]Oxygen and zinc abundances in 417 Galactic bulge red giants

We report results from an exploratory study implementing a new probe of Galactic evolution using archival Hubble Space Telescope imaging observations. Precise proper motions are combined with photometric relative metallicity and temperature indices, to produce the proper-motion rotation curves of...


Clarkson, W.I.Calamida, A.Sahu, K.C.Brown, T.M.Gennaro, M.Avila, R.J.Valenti, J.Debattista, V.P.Rich, R.M.Minniti, D.Zoccali, M.Aufdemberge, E.R.[Chemically Dissected Rotation Curves of the Galactic Bulge from Main-sequence Proper Motions]Chemically Dissected Rotation Curves of the Galactic Bulge from Main-sequence Proper Motions

Deep near-IR images from the VISTA Variables in the V a L ctea (VVV) Survey were used to search for RR Lyrae stars within 100 arcmin from the Galactic Center. A large sample of 960 RR Lyrae of type ab (RRab) stars were discovered. A catalog is presented featuring the positions, magnitudes, colors...

The Hubble Space Telescope/WFC3 multiband photometry spanning from the UV to the near-IR of four fields in the Galactic bulge, together with that for six template globular and open clusters, are used to photometrically tag the metallicity [Fe/H] of stars in these fields after proper-motion reject...


Renzini, A.Gennaro, M.Zoccali, M.Brown, T.M.Anderson, J.Minniti, D.Sahu, K.C.Valenti, E.Vandenberg, D.A.[The WFC3 Galactic Bulge Treasury Program: Relative Ages of Bulge Stars of High and Low Metallicity]The WFC3 Galactic Bulge Treasury Program: Relative Ages of Bulge Stars of High and Low Metallicity

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...
