Stellar density profile and mass of the Milky Way Bulge from VVV data
E. Valenti, M. Zoccali, O. A. Gonzalez +6
We present the first stellar density profile of the Milky Way bulge reaching latitude . It is derived by counting red clump stars within the colour\--magnitude diagram c…
Reinforcing the link between the double red clump and the X-shaped bulge of the Milky Way
O. A. Gonzalez, M. Zoccali, Victor P. Debattista +3
The finding of a double red clump in the luminosity function of the Milky Way bulge has been interpreted as evidence for an X-shaped structure. Recently, an alternative explanation…
Interstellar Extinction Curve Variations Toward the Inner Milky Way: A Challenge to Observational Cosmology
David M. Nataf, Oscar A. Gonzalez, Luca Casagrande +18
We investigate interstellar extinction curve variations toward 4 deg of the inner Milky Way in photometry from the OGLE-III and surveys, with supportin…
The Giraffe Inner Bulge Survey (GIBS) II. Metallicity distributions and alpha element abundances at fixed Galactic latitude
O. A. Gonzalez, M. Zoccali, S. Vasquez +8
High resolution (R22,500) spectra for 400 red clump giants, in four fields within and $\rm -10^{\circ} \lesssim l \lesssim…
Massive Stars in the W33 Giant Molecular Complex
Maria Messineo, J. Simon Clark, Donald F. Figer +9
Rich in HII regions, giant molecular clouds are natural laboratories to study massive stars and sequential star formation. The Galactic star forming complex W33 is located at l=~12…
