The Gaia-ESO Survey: Exploring the complex nature and origins of the Galactic bulge populations [PDF]
, 2017 Context. As observational evidence steadily accumulates, the nature of the Galactic bulge has proven to be rather complex: the structural, kinematic, and chemical analyses often lead to contradictory conclusions.

Deep Hubble Space Telescope Imaging of Globular Clusters toward the Galactic Bulge: Observations, Data Reduction, and Color–magnitude Diagrams [PDF]
Astronomical Journal, 2018 The Galactic globular clusters (GGCs) located toward the Galactic bulge have generally been excluded from large-scale photometric GGC surveys due to severe total and differential extinction.

The Nuclear Bulge of the Galaxy. III. Large-Scale Physical Characteristics of Stars and Interstellar Matter [PDF]
, 2002 We analyse IRAS and COBE DIRBE data at wavelengths between 2.2 and 240 mu of the central 500pc of the Galaxy and derive the large-scale distribution of stars and interstellar matter in the Nuclear Bulge.

RR Lyrae Variables as Tracers of the Galactic Bulge Kinematic Structure
Universe, 2022 RR Lyrae stars are recognized as some of the oldest stars in the Universe. In addition, they are some of the few old celestial objects for which distances can be reliably inferred.

Chemodynamical modelling of the galactic bulge and bar [PDF]
, 2017 We present the first self-consistent chemodynamical model fitted to reproduce data for the galactic bulge, bar and inner disk. We extend the Made-to-Measure method to an augmented phase-space including the metallicity of stars, and show its first ...

Weighing the two stellar components of the Galactic bulge [PDF]
Astronomy & Astrophysics, 2018 Context.Recent spectroscopic surveys of the Galactic bulge have unambiguously shown that the bulge contains two main components, which are best separated by their iron content, but also differ in spatial distribution, kinematics, and abundance ratios ...

Chemically Dissected Rotation Curves of the Galactic Bulge from Main-sequence Proper Motions [PDF]
, 2018 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 ...

A boxy bulge in the Milky Way. Inversion of the stellar statistics equation with 2MASS data [PDF]
, 2005 Inverting the stellar statistics equation from 2MASS star counts, we obtain the 3D density distribution of the Galactic bulge as well as its luminosity function in the K-band.
