Separation of Stellar Populations by an Evolving Bar: Implications for the Bulge of the Milky Way
Victor P. Debattista, Melissa Ness, Oscar A. Gonzalez +3
We present a novel interpretation of the previously puzzling different behaviours of stellar populations of the Milky Way's bulge. We first show, by means of pure N-body simulation…
The GIRAFFE Inner Bulge Survey (GIBS) III. Metallicity distributions and kinematics of 26 Galactic bulge fields
M. Zoccali, S. Vasquez, O. A. Gonzalez +9
Several recent studies have demonstrated that the Galactic bulge hosts two components with different mean metallicities, and possibly different spatial distribution and kinematics.…
The VLT LBG Redshift Survey - VI. Mapping HI in the proximity of LBGs with X-Shooter
R. M. Bielby, T. Shanks, N. H. M. Crighton +6
We present an analysis of the spatial distribution of gas and galaxies using new X-Shooter observations of quasars. Adding the X-Shooter data to an existing dataset of h…
Young Stellar Clusters Containing Massive Young Stellar Objects in the VVV Survey
J. Borissova, S. Ramírez Alegría, J. Alonso +17
The purpose of this research is to study the connection of global properties of eight young stellar clusters projected in the Vista Variables in the Via Lactea (VVV) ESO Large Publ…
A machine learned classifier for RR Lyrae in the VVV survey
Felipe Elorrieta, Susana Eyheramendy, Andrés Jordán +10
Variable stars of RR Lyrae type are a prime tool to obtain distances to old stellar populations in the Milky Way, and one of the main aims of the Vista Variables in the Via Lactea…
Discovery of RR Lyrae Stars in the Nuclear Bulge of the Milky Way
D. Minniti, R. Contreras Ramos, M. Zoccali +4
Galactic nuclei, like the one of the Milky Way, are extreme places with high stellar densities and, in most cases, hosting a supermassive black hole. One of the scenarios proposed…
