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, thicker and shorter, with a smaller tilt respect to the Sun-GC line, has been a matter of discussion in recent decades. Aims. In this paper, we present low resolution ($R=500$) near-infrared spectra for selected and serendipitous sources in six inner in-plane Galactic fields at $l=7^\circ$, 12°, 15… 
THE DISTANCE, MASS, AND RADIUS OF THE NEUTRON STAR IN 4U 1608-52
Low-mass X-ray binaries (LMXBs) that show thermonuclear bursts are ideal sources for constraining the equation of state of neutron star matter. The lack of independent distance measurements for most
Infrared Extinction in the Inner Milky Way through Red Clump Giants
While the shape of the extinction curve in the infrared is considered to be set and the extinction ratios between infrared bands are usually taken to be approximately constant, a number of recent
A K-band spectral mini-survey of Galactic B[e] stars
We present a mini-survey of Galactic B[e] stars mainly undertaken with the Large Binocular Telescope (LBT). B[e] stars show morphological features with hydrogen emission lines and an infrared excess,
The Quintuplet cluster - III. Hertzsprung-Russell diagram and cluster age
The Quintuplet, one of three massive stellar clusters in the Galactic center (GC), is located about 30 pc in projection from Sagittarius A*. We aim at the construction of the Hertzsprung-Russell
One of the most massive stars in the Galaxy may have formed in isolation
Very massive stars, 100 times heavier than the sun, are rare. It is not yet known whether such stars can form in isolation or only in star clusters. The answer to this question is of fundamental
The Quintuplet cluster - I. A K-band spectral catalog of stellar sources
Context. Three very massive clusters are known to reside in the Galactic center region, the Arches cluster, the Quintuplet cluster, and the central parsec cluster, each of them rich in young hot
Another cluster of red supergiants close to RSGC1
Context. Recent studies have revealed massive star clusters in a region of the Milky Way close to the tip of the Long Bar. These clusters are heavily obscured and are characterised by a population of
The origin of the Galactic center diffuse X-ray emission investigated by near-infrared imaging and polarimetric observations
Abstract The origin of the Galactic center diffuse X-ray emission (GCDX) is still under intense investigation. We have found a clear excess in a longitudinal GCDX profile over a stellar number
Analysis of the WN star WR 102c, its WR nebula, and the associated cluster of massive stars in the Sickle Nebula
The massive Wolf-Rayet type star WR 102c is located near the Quintuplet Cluster - one of the three massive star clusters in the Galactic Center region. Previous studies indicated that WR 102c may
The phase space of boxy–peanut and X-shaped bulges in galaxies – II. The relation between face-on and edge-on boxiness
We study the dynamical mechanisms that reinforce the formation of boxy structures in the inner regions, roughly in the middle, of bars observed nearly face-on. Outer boxiness, at the ends of the

Metallicity of Red Giants in the Galactic Bulge from Near-Infrared Spectroscopy
We present moderate-resolution (λ/Δλ = 1300–4800) K-band spectra of more than 110 M giants in Galactic bulge fields interior to -4° (560 pc) and as close as within 02 (28 pc) of the Galactic center.
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
Infrared stellar populations in the central parts of the Milky Way galaxy
Near- and mid-IR survey data from DENIS and ISOGAL are used to investigate the structure and formation history of the inner 10 ◦ (1.4 kpc) of the Milky Way galaxy. Synthetic bolometric corrections
Detection of the old stellar component of the major Galactic bar

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,
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

The light distribution in the inner few kiloparsecs of the Milky Way is recovered non­ parametrically from a dust-corrected near-infrared COBEIDIRBE surface brightness map of the inner Galaxy. The
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
