The Galactic Bulge [PDF]

open access: yesPublications of the Astronomical Society of Australia, 2019
We will revise different aspects of the Galactic bulge, including in particular metallicities and ages of its stellar content.

Abundances in the Galactic bulge [PDF]

open access: yesPhysica Scripta, 2016
The metallicity distribution and abundance ratios of the Galactic bulge are reviewed. Issues raised by recent work of different groups, in particular the high metallicity end, the overabundance of α-elements in the bulge relative to the thick disc and ...

Dust properties in the Galactic bulge [PDF]

open access: yesAstronomy & Astrophysics, 2013
Context. It has been suggested that the ratio of total-to-selective extinction R-V in dust in the interstellar medium differs in the Galactic bulge from its value in the local neighborhood.Aims. We attempt to test this suggestion.Methods.

The formation of galactic bulges [PDF]

open access: yesProceedings 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]

open access: yesProceedings 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.

GALACTIC BULGES

open access: yesAnnual 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

Galactic microlensing : binary-lens light curve morphologies and results from the Rosetta spacecraft bulge survey [PDF]

open access: yes, 2014
For 20 years now, gravitational microlensing observations towards the Galactic bulge have provided us with a wealth of information about the stellar and planetary content of our Galaxy, which is inaccessible via other current methods.

The 3D Structure of the Galactic Bulge [PDF]

open access: yesPublications of the Astronomical Society of Australia, 2016
AbstractWe review the observational evidences concerning the three-dimensional structure of the Galactic bulge. Although the inner few kpc of our Galaxy are normally referred to asthe bulge, all the observations demonstrate that this region is dominated by a bar, i.e., the bulge is a bar.

Hot Subdwarfs in the Galactic Bulge [PDF]

open access: yesThe Astrophysical Journal, 2005
Recent observations and theories suggest that extreme horizontal branch (EHB) stars and their progeny should be the cause of the UV excess seen in the spectra of many elliptical galaxies. Since the Galactic Bulge is the closest representation of an old, metal-rich spheroid in which we are able to study the EHB scenario in detail, we obtained spectra of
