The GLIMPSE (Galactic Legacy Mid-Plane Survey Extraordinaire) Point Source Catalog of ~30 million mid-infrared sources toward the inner Galaxy, 10° ≤ |l| ≤ 65° and |b| ≤ 1°, was used to determine the distribution of stars in Galactic longitude, l, latitude, b, and apparent magnitude, m. The counts versus longitude can be approximated by the modified Bessel function N = N0(l/l0)K1(l/l0), where l0 is insensitive to limiting magnitude, band choice, and side of Galactic center: l0 = 17°-30° with a… Expand
We present a highly reliable flux-limited census of 18,949 point sources in the Galactic midplane that have intrinsically red mid-infrared colors. These sources were selected from the Spitzer SpaceExpand
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 ofExpand
The structure of the Milky Way's bar outside the bulge
While it is incontrovertible that the inner Galaxy contains a bar, its structure near the Galactic plane has remained uncertain, where extinction from intervening dust is greatest. We investigateExpand
Large-scale latitude distortions of the inner Milky Way disk from the Herschel/Hi-GAL Survey
Aims. We use the Herschel Hi-GAL survey data to study the spatial distribution in Galactic longitude and latitude of the interstellar medium and of dense, star-forming clumps in the inner Galaxy.Expand
In this Letter, we present a search for Galactic red supergiant stars (RSGs) in the direction of the inner Galaxy. A total of 94 targets selected from the 2MASS and GLIMPSE I North catalogs—via theirExpand
The stellar population structure of the Galactic disk
The spatial structure of stellar populations with different chemical abundances in the Milky Way contains a wealth of information on Galactic evolution over cosmic time. We use data on 14,699Expand
The Bubbling Galactic Disk. II. The Inner 20
We report 269 mid-infrared bubbles within 10° of the Galactic center from visual inspection of the Spitzer GLIMPSE II Legacy Science program images. The surface density of bubbles is ~5 deg-2 orExpand
Stellar Overdensity in the Local Arm in Gaia DR2
Using the cross-matched data of Gaia DR2 and 2MASS Point Source Catalog, we investigated the surface density distribution of stars aged ~1 Gyr in the thin disk in the range of 90° <= l <= 270°. WeExpand
The VVV near-IR galaxy catalogue beyond the Galactic disc
Knowledge about the large-scale distribution of galaxies is far from complete in the Zone of Avoidance, which is mostly due to high interstellar extinction and to source confusion at lower GalacticExpand
The Red MSX Source survey: distribution and properties of a sample of massive young stars
The Red MSX Source (RMS) survey has identified a large sample of massive young stellar objects and ultra compact H II regions from a sample of ~2000 MSX and Two Micron All Sky Survey (2MASS) colourExpand


Detection of the old stellar component of the major Galactic bar
We present near-infrared colour–magnitude diagrams and star counts for a number of regions along the Galactic plane. It is shown that along the l=27°, b=0° line of sight there is a feature at 5.7±0.7Expand
The Wavelength Dependence of Interstellar Extinction from 1.25 to 8.0 μm Using GLIMPSE Data
We determine and tabulate A[λ]/AK, the wavelength dependence of interstellar extinction, in the Galactic plane for 1.25 μm ≤ λ ≤ 8.0 μm along two lines of sight: l = 42° and 284°. The first is aExpand
A model of the 8-25 micron point source infrared sky
We present a detailed model for the IR point-source sky that comprises geometrically and physically realistic representations of the Galactic disk, bulge, stellar halo, spiral arms (including theExpand
COBE's 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,Expand

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,Expand
Gas dynamics and large-scale morphology of the Milky Way galaxy
We present a new model for the gas dynamics in the galactic disc inside the orbit of the Sun. Quasi-equilibrium flow solutions are determined in the gravitational potential of the deprojected COBEExpand
The Structure of Four Molecular Cloud Complexes in the BU-FCRAO Milky Way Galactic Ring Survey
We present a study of the structure of four molecular clouds from the Milky Way Galactic Ring Survey (GRS), a Boston University and Five College Radio Astronomy Observatory collaboration. The GRS isExpand
A Model of the 2-35 micron Point Source Infrared Sky
The Point Source Infrared Sky Model of Wainscoat et al. [ApJS, 83, 111 (1992)] is extended to make predictions for any filter lying wholly within the range 2.0 to 35.0 μm. The development of aExpand
The relationship between infrared, optical, and ultraviolet extinction
The parameterized extinction data of Fitzpatrick and Massa (1986, 1988) for the ultraviolet and various sources for the optical and near-infrared are used to derive a meaningful average extinctionExpand
