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 examine DENIS and Two Micron Galactic Survey star counts for the characteristic signatures of an in-plane bar and ring. The star counts in the plane for $30^\circ> l> -30^\circ$ are shown to be highly asymmetric with considerably more sources at positive than at negative longitudes. At $|b|\approx… 
The long Galactic bar as seen by UKIDSS Galactic plane survey
Context. Over the past decade there have been a series of results supporting the 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
Another bar in the Bulge
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
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
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,
Old stellar Galactic disc in near-plane regions according to 2MASS: Scales, cut-off, flare and warp
We have pursued two dierent methods to analyze the old stellar population near the Galactic plane, using data from the 2MASS survey. The first method is based on the isolation of the red clump giant
An analysis of star formation with Herschel in the Hi-GAL Survey: II. the tips of the Galactic bar
Context. We present the physical and evolutionary properties of prestellar and protostellar clumps in the Herschel Infrared GALactic plane survey (Hi-GAL) in two large areas centered in the Galactic
Stellar density distribution in the NIR on the Galactic plane at longitudes 15-27 deg. Clues for the Galactic bar?
Garzon et al. (1997), Lopez-Corredoira et al. (1999) and Hammersley et al. (2000) have identified in TMGS and DENIS data a large excess of stars at l = 27 ◦ and b = 0 ◦ which might correspond to an
The structure of the Galactic bar
We present a deep near-infrared wide-angle photometric analysis of the structure of the inner Galactic bar and central disc. The presence of a triaxial structure at the centre of the Galaxy is
Evidence for a deficit of young and old stars in the Milky Way inner in-plane disc
We give independent proof of the deficit of stars in the in-plane central disc (2 < R < 4 kpc, |b| <∼ 3°) with respect to the predictions of a pure exponential density distribution. We use three
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


A COBE Model of the Galactic Bar and Disk
A model of the bar and old stellar disk of the Galaxy has been derived from the survey of the Diffuse Infrared Background Experiment (DIRBE) of the Cosmic Background Explorer at wavelengths of 1.25,
A Major Star Formation Region in the Receding Tip of the Stellar Galactic Bar
We present an analysis of the optical spectroscopy of 58 stars in the Galactic plane at l=27°, where a prominent excess in the flux distribution and star counts have been observed in several spectral

A method based on Lucy (1974) iterative algorithm is developed to invert the equation of stellar statistics for the Galactic bulge and is then applied to the K-band star counts from the Two-Micron

Longitude-velocity (l-V) diagrams of H I and CO gas in the inner Milky Way have long been known to be inconsistent with circular motion in an axisymmetric potential. Several lines of evidence suggest
Variations of the selective extinction across the galactic bulge - implications for the galactic bar
We propose a new method to investigate the coefficient of the selective extinction, based on two band photometry. This method uses red clump stars as a means to construct the reddening curve. We
