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 ...

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 ...

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.

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

The Galactic bulge: a review [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractThe 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 progress in the understanding of the Milky Way central region: the bulge.

The Far Side of the Galactic Bar/Bulge Revealed through Semi-regular Variables
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.

Annual Review of Astronomy and Astrophysics, 1997 ▪ Abstract We discuss the present observational and theoretical understanding of the stellar populations of bulges and their implications for galaxy formation and evolution. The place of bulges as key to the Hubble Sequence remains secure, but some old paradigms are giving way to new ones as observations develop. Detailed studies of Local Group bulges

Tracking millisecond pulsars responsible for the Fermi GeV excess [PDF]
EPJ Web of Conferences, 2023 More than 10 years ago, an excess of γ-ray photons coming from the Galactic center was discovered in the Fermi-LAT data. First attributed to dark matter, it has since been shown that it should have at least a partial stellar origin. One hypothesis is the

The Astrophysical Journal, 2023 We present wide-field, high resolution maps of the color excess for 14 globular clusters toward the Southern Galactic bulge. The maps were derived using Gaia EDR3 astrometry and stellar photometry from the Blanco DECam Bulge Survey, which is a deep, wide-
