Microlensing Constraints on Primordial Black Holes toward the Bulge Are Galactic Model Limited
The Astrophysical JournalPostulated to form from density fluctuations in the early Universe, primordial black holes (PBHs) could constitute some fraction of dark matter (DM).

Astronomy & AstrophysicsIn this paper, we present the chemical screening of the stellar population belonging to the globular cluster NGC 6553 in the Galactic bulge. This study has been conducted in the contest of the Bulge Cluster Origin (BulCO) survey, an ESO-VLT Large Program

Advances in Astronomy, 2015 In recent years free-floating planets (FFPs) have drawn a great interest among astrophysicists. Gravitational microlensing is a unique and exclusive method for their investigation which may allow obtaining precious information about their mass and ...

The Transition between the Inner Disc and the Innermost Galactic Regions
, 2015 We discuss the iron and the α-element gradients in the Galactic disc and in the innermost Galactic regions (bulge, bar, nuclear bulge). Accurate spectroscopic measurements of young stellar tracers show a well defined iron gradient between the inner and ...

Orientation of Galactic Bulge Planetary Nebulae toward the Galactic Center [PDF]
, 2016 We have used the Wide Field Spectrograph on the Australian National University 2.3-m telescope to perform the integral field spectroscopy for a sample of the Galactic planetary nebulae.

Review of the Galactic Bulge [PDF]
Symposium - International Astronomical Union, 1993 For sins that I have been unable to identify, I have been asked to give a review talk on the Galactic bulge. This is a subject to which I have not been very close in recent years, so that I have been able to approach it with a fairly open mind, though I must acknowledge a lot of generous help from Mike Rich, Don Terndrup, and Jay Frogel. But any errors,

Kinematics and composition of the Galactic bulge: recent progress
, 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).

Formation Models of the Galactic Bulge
, 2014 The Galactic bulge is now considered to be the inner three-dimensional part of the Milky Way's bar. It has a peanut shape and is characterized by cylindrical rotation. In N-body simulations, box/peanut bulges arise from disks through bar and buckling instabilities.

Composition of the Galactic bulge
, 2003 We present detailed abundance results for 9 Galactic bulge stars in Baade's Window, based on HIRES (R=45,000--60,000) spectra taken with the Keck I telescope. The alpha elements show non-uniform enhancements relative to the Solar neighborhood trends: Mg and Si are enhanced in all our bulge stars by $\sim$0.5--0.3 dex, showing a slight decrease with ...
