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 ...

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.

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.

GRBs and the 511 keV emission of the Galactic bulge [PDF]
, 2004 We consider the phenomenology of the 511 keV emission in the Galactic bulge, as recently observed by INTEGRAL, and propose a model is which the positrons are produced by gamma-ray bursts (GRB) associated with mini starbursts in the central molecular zone

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-

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.

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.

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).

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.
