New kinematic map of the Milky Way bulge
Carlos Quezada, Manuela Zoccali, Elena Valenti +7
The kinematics of the Milky Way bulge is known to be complex, reflecting the presence of multiple stellar components with distinct chemical and spatial properties. In particular, t…
The VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey: Completion of the observations and legacy
R. K. Saito, M. Hempel, J. Alonso-García +143
The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from . Upon its conclusion, the c…
The imprint of clump formation at high redshift. II. The chemistry of the bulge
Victor P. Debattista, David J. Liddicott, Oscar A. Gonzalez +11
In Paper I we showed that clumps in high-redshift galaxies, having a high star formation rate density (Σ_SFR), produce disks with two tracks in the [Fe/H]-[α/Fe] chemical space, si…
Testing for relics of past strong buckling events in edge-on galaxies: Simulation predictions and data from SG
V. Cuomo, V. P. Debattista, S. Racz +7
The short-lived buckling instability is responsible for the formation of at least some box/peanut (B/P) shaped bulges, which are observed in most massive, , barred galaxies. N…
Predicted Trends in Milky Way Bulge Proper Motion Rotation Curves: future Prospects for HST and LSST
Steven Gough-Kelly, Victor P. Debattista, William I. Clarkson +5
We use an -body+smoothed particle hydrodynamics simulation of an isolated barred galaxy to study the age dependence of bulge longitudinal proper motion () rotation curves.…
A new distance to the Brick, the dense molecular cloud G0.253+0.016
M. Zoccali, E. Valenti, F. Surot +3
We analyse the near infrared colour magnitude diagram of a field including the giant molecular cloud G0.253+0.016 (a.k.a. The Brick) observed at high spatial resolution, with HAWK-…
