Chemodynamical History of the Galactic Bulge [PDF]
Annual Review of Astronomy and Astrophysics, 2018 The Galactic Bulge can uniquely be studied from large samples of individual stars and is therefore of prime importance for understanding the stellar population structure of bulges in general. Here the observational evidence on the kinematics, chemical composition, and ages of Bulge stellar populations based on photometric and spectroscopic data is ...

Kinematics and Composition of the Galactic Bulge: Recent Progress [PDF]
, 2007 We present recent results from a Keck study of the composition of the Galactic bulge, as well as results from the bulge Bulge Radial Velocity Assay (BRAVA). Culminating a 10 year investigation, Fulbright, McWilliam, & Rich (2006, 2007) solved the problem

Microlensing Towards the Galactic Bulge [PDF]
Symposium - International Astronomical Union, 1993 We describe an ongoing survey to search for dark matter via lensing events of stars in the Galactic Bulge. The principal properties of the survey are described, and some preliminary results are shown for newly-discovered variables. We discuss some of the projects related to the study of the Galactic Bulge that can be addressed using these data, and ...

The formation of galactic bulges [PDF]
Proceedings of Baryons in Dark Matter Halos — PoS(BDMH2004), 2004 We summarise some recent results about nearby galactic bulges, relevant to their formation. We highlight a number of significant advances in our understanding of the surface brightness profiles, stellar populations, and especially the very centers of spirals. We also view our own Milky Way as if it were an external galaxy. Our main conclusions are that

ARGOS – II. The Galactic bulge survey [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 Abstract We describe the motivation, field locations and stellar selection for the Abundances and Radial velocity Galactic Origins Survey (ARGOS) spectroscopic survey of 28 000 stars in the bulge and inner disc of the Milky Way galaxy across latitudes of b = −5° to −10°.

The chemical evolution of the Galactic Bulge seen through micro-lensing events
EPJ Web of Conferences, 2012 Galactic bulges are central to understanding galaxy formation and evolution. Here we report on recent studies using micro-lensing events to obtain spectra of high resolution and moderately high signal-to-noise ratios of dwarf stars in the Galactic bulge.

X-ray Insight into High-Energy Processes in Extreme Galactic Nuclear Environment
Universe, 2022 Nuclear regions of galaxies apparently play a disproportionately large role in regulating their formation and evolution. How this regulation works, however, remains very uncertain.

Radio detection prospects for a bulge population of millisecond pulsars as suggested by Fermi LAT observations of the inner Galaxy [PDF]
, 2016 Analogously to globular clusters, the dense stellar environment of the Galactic center has been proposed to host a large population of as-yet undetected millisecond pulsars (MSPs).

Thick disk and pseudobulge formation in a clump cluster
EPJ Web of Conferences, 2012 Bulges in spiral galaxies have been supposed to be classified into two types: classical bulges or pseudobulges. Classical bulges are thought to form by galactic merger with bursty star formation, whereas pseudobulges are suggested to form by secular ...

Prediction of Planet Yields by the PRime-focus Infrared Microlensing Experiment Microlensing Survey
The Astronomical Journal, 2023 The PRime-focus Infrared Microlensing Experiment (PRIME) will be the first to conduct a dedicated near-infrared microlensing survey by using a 1.8 m telescope with a wide field of view of 1.45 deg ^2 at the South African Astronomical Observatory.
