The Habitability of the Galactic Bulge [PDF]
Life, 2020 We present a new investigation of the habitability of the Milky Way bulge, that expands previous studies on the Galactic Habitable Zone. We discuss existing knowledge on the abundance of planets in the bulge, metallicity and the possible frequency of ...

The Far Side of the Galactic Bar/Bulge Revealed through Semi-regular Variables [PDF]
The Astronomical Journal, 2023 The Galactic bulge is critical to our understanding of the Milky Way. However, due to the lack of reliable stellar distances, the structure and kinematics of the bulge/bar beyond the Galactic center have remained largely unexplored.

Monthly Notices of the Royal Astronomical Society, 2000 We model the evolution of the galactic bulge and of the bulges of a selected sample of external spiral galaxies, via the multiphase multizone evolution model.

Transiting Exoplanet Yields for the Roman Galactic Bulge Time Domain Survey Predicted from Pixel-level Simulations [PDF]
The Astrophysical Journal Supplement Series, 2023 The Nancy Grace Roman Space Telescope (Roman) is NASA’s next astrophysics flagship mission, expected to launch in late 2026. As one of Roman’s core community science surveys, the Galactic Bulge Time Domain Survey (GBTDS) will collect photometric and ...

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 ...

The Galactic Bulge: A Review [PDF]
Proceedings of the International Astronomical Union, 2007 The Milky Way is the only galaxy for which we can resolve individual stars at all evolutionary phases, from the Galactic center to the outskirt. The last decade, thanks to the advent of near IR detectors and 8 meter class telescopes, has seen a great ...

Maximum Entropy Estimation of the Galactic Bulge Morphology via the VVV Red Clump [PDF]
Monthly notices of the Royal Astronomical Society, 2020 The abundance and narrow magnitude dispersion of Red Clump (RC) stars make them a popular candidate for mapping the morphology of the bulge region of the Milky Way.

The COMBS survey I : Chemical Origins of Metal-Poor Stars in the Galactic Bulge [PDF]
Monthly notices of the Royal Astronomical Society, 2019 19 pages, 5 tables, accepted to MNRASChemistry and kinematic studies can determine the origins of stellar population across the Milky Way. The metallicity distribution function of the bulge indicates that it comprises multiple populations, the more metal-

Positron Transport and Annihilation in the Galactic Bulge [PDF]
Galaxies, 2018 The annihilation of positrons in the Milky Way Galaxy has been observed for ∼50 years; however, the production sites of these positrons remains hard to identify.
