A map of the projected density of the old stellar population of the Galactic Bulge region is reconstructed using 2MASS data. By making a combination of the H and K photometric bands, it is possible to overcome the eect of reddening, and thus penetrate the inner structure of the Galactic Bulge. The main structure in the map corresponds to the well documented peanut shaped bar which is formed by the inner parts of the Galactic disk as a result of dynamical instabilities. As suggested by numerical…

Recent data from the VVV survey have strengthened evidence for a structural change in the Galactic bulge inward of |l| ⩽ 4°. Here we show with an N-body barred galaxy simulation that a boxy bulge

Tracing the long bar with red-clump giants

Context. Over the last decade a series of results have lent support to t he hypothesis of the existence of a long thin bar in the Milky Way with a half-length of 4.5 kpc and a position angle of

Stellar populations in the Milky Way bulge region: towards solving the Galactic bulge and bar shapes using 2MASS data

Exploring the bulge region of our Galaxy is an interesting but challenging quest because of its complex structure and the highly variable extinction. We re-analyse photometric near-infrared data in

Gaia: new perspectives in understanding the galactic bulge

Although the Milky Way bulge is our closest opportunity to study in detail such a complex chemo-dynamical system, its formation and evolution is still poorly understood. The high extinction, the

Metallicity distribution of red giants in the Inner Galaxy from near infrared spectra

Context. The existence in the Milky Way of either a long thin bar with a half length of 4.5 kpc and a position angle of around 45° with respect to the Sun-Galactic centre line or a bulge+bar complex,

The 3D Structure of the Galactic Bulge

Abstract We 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 as the bulge, all

Gas flow models in the Milky Way embedded bars

Context. The gas distribution and dynamics in the inner Galaxy present many unknowns, such as the origin of the asymmetry of the lu-diagram of the Central Molecular Zone (CMZ). On the other hand,

The Long Bar in the Milky Way: Corroboration of an Old Hypothesis

Recent Galactic Legacy Infrared Mid-Plane Survey Extraordinaire data have further confirmed the hypothesis of the existence of an in-plane long bar different from the bulge of the Milky Way with the


Motivated by recent observations that suggest a low density of old stars around the Milky Way supermassive black hole (SMBH), models for the nuclear star cluster are considered that have not yet

The inner Galactic bar traced by the VVV survey

Aims. We use the VVV survey observations in bulge regions close to the Galactic plane to trace the bar inclination at the Galactic latitude b ∼± 1 and to investigate a distinct structure in the inner

Searching for the in-plane Galactic bar and ring in DENIS

New evidence for a long thin Galactic bar (in contradistinction to the bulge), as well as for the existence of the ring and the truncation of the inner disc, are sought in the DENIS survey. First, we

Surface photometry of spiral galaxies in NIR: Structural parameters of disks and bulges

A sample of 40 bright spiral galaxies (BT < 12) with low inclination and without bar was observed with JHK lters. For this purpose the MAGIC NICMOS3 camera at the 2.2 m telescope of the Calar Alto

Morphology, near infrared luminosity, and mass of the galactic bulge from Cobe dirbe observations

Near-infrared images of the Galactic bulge at 1.25, 2.2, 3.5, and 4.9 microns obtained by the Diffuse Infrared Background Experiment (DIRBE) onboard the Cosmic Background Explorer (COBE) satellite


The color-magnitude diagrams of $\sim 5\times 10^5$ stars obtained for 13 fields towards the Galactic bulge with the OGLE project reveal a well-defined population of bulge red clump stars. We find

Nuclear bars and blue nuclei within barred spiral galaxies

Multicolour near IR photometry for a sample of 32 large barred spiral galaxies is presented. By applying ellipse fitting techniques, we identify significant isophote twists with respect to the

Direct evidence for a bar at the Galactic center

The bar at the center of the Milky Way, long postulated from a number of different studies, is unambiguously detected in the 2.4 μm observations of the Galactic center of Matsumoto et al. We model

Triple Bars and Complex Central Structures in Disk Galaxies

We present an analysis of ground-based and Hubble Space Telescope images of three early-type barred galaxies. The first, NGC 2681, may be the clearest example yet of a galaxy with three concentric

Orbits supporting bars within bars

High-resolution observations of the inner regions of barred disc galaxies have revealed many asymmetrical, small-scale central features, some of which are best described as secondary bars. Because

Hubble Space Telescope Optical-Near-Infrared Colors of Nearby R 1/4 and Exponential Bulges

We have analyzed V, H, and J Hubble Space Telescope (HST) images for a sample of early- to late-type spiral galaxies and have reported elsewhere the statistical frequency of R 1/4-law and exponential

We present detailed JHK surface photometry with ellipse ts of 13 galaxies selected from previous optical observations as likely candidates for having a secondary bar or a triaxial bulge within the
