Aims. The Two Micron All Sky Survey, along with the Stellar Population Synthesis Model of the Galaxy, developed in Besancon, is used to calculate the extinction distribution along different lines of sight. By combining many lines of sight, the large scale distribution of interstellar material can be deduced. Methods. The Galaxy model is used to provide the intrinsic colour of stars and their probable distances, so that the near infrared colour excess, and hence the extinction, may be calculated… 
Three-dimensional interstellar extinction map toward the Galactic bulge
Context. Studies of the properties of the inner Galactic bulge strongly depend on the assumptions made about interstellar extinction. Most of the extinction maps available in the literature lack the
The Gaia-ESO Survey: Tracing interstellar extinction
Context. Large spectroscopic surveys have in recent years enabled computing three-dimensional interstellar extinction maps thanks to the accurate stellar atmospheric parameters and line-of-sight
On Galactic density modeling in the presence of dust extinction
Inferences about the spatial density or phase-space structure of stellar populations in the Milky Way require a precise determination of the effective survey volume. The volume observed by surveys
The Milky Way's external disc constrained by 2MASS star counts
Context. Thanks to recent large-scale surveys in the near infrared, such as 2MASS, the galactic plane that most suffers from extinction is revealed so its overall structure can be studied. Aims. This
Investigation of the stellar population and determination of interstellar extinction toward the Chandra Bulge Field based on RTT-150 data
We have investigated the stellar population of the Chandra Bulge Field (CBF) 35′ × 35′ in area using the Russian-Turkish RTT-150 telescope with the goal of constructing an interstellar extinction map
Estimation of Galactic model parameters in high latitudes with 2MASS
Context. In general, studies focused on the Milky Way's structure show a range of values when deriving different Galactic parameters, such as radial scalelengths, vertical scaleheights, or local
Interstellar extinction and the distribution of stellar populations in the direction of the ultra-deep Chandra Galactic field
We studied the stellar population in the central 6.6x6.6arcmin,region of the ultra-deep (1Msec) Chandra Galactic field - the "Chandra bulge field" (CBF) approximately 1.5 degrees away from the
The structure of molecular clouds – I. All-sky near-infrared extinction maps
We are studying the column density distribution of all nearby giant molecular clouds. As part of this project, we generated several all-sky extinction maps. They are calculated using the median
Detection of the Milky Way spiral arms in dust from 3D mapping
Large stellar surveys are sensitive to interstellar dust through the effects of reddening. Using extinctions measured from photometry and spectroscopy, together with three-dimensional (3D) positions
Mapping the Milky Way bulge at high resolution: the 3D dust extinction, CO, and X factor maps
Three dimensional interstellar extinction maps provide a powerful tool for stellar population analysis. We use data from the VISTA Variables in the Via Lactea survey together with the Besan\c{c}on


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
Three-dimensional Structure of the Milky Way Disk: The Distribution of Stars and Dust beyond 0.35 R☉
We present a three-dimensional model for the Milky Way fitted to the far-infrared (FIR) and near-infrared (NIR) data from the COBE/DIRBE instrument for Galactic latitudes |b| < 30° and to within 20°
Large-scale variations of the dust optical properties in the Galaxy
We present an analysis of the dust optical properties at large scale, for the whole galactic anticenter hemisphere. We used the 2MASS Extended Source Catalog to obtain the total reddening on each
A Galactic Plane relative extinction map from 2MASS
We present three 14 400 square degree relative extinction maps of the Galactic Plane (|b| < 20°) obtained from 2MASS using accumulative star counts (Wolf diagrams). This method is independent of the
A synthetic view on structure and evolution of the Milky Way
Since the Hipparcos mission and recent large scale surveys in the optical and the near-infrared, new constraints have been obtained on the structure and evolution history of the Milky Way. The
The Structure of Our Galaxy Derived from Observations of Neutral Hydrogen
Although insight into the structure of our Galaxy can be sought in various ways, study of the radio emission from the neutral hydrogen component is particularly suitable. Neutral atomic hydrogen, HI,
The Vertical Distribution and Kinematics of H i and Mass Models of the Galactic Disk
We present full modeling of tangent point emission of HI as seen in the 21 cm transition in the inner Galaxy ($R \simeq 3-8 \kpc$). The model used takes into account emission from a large path length
Abundance Gradients and the Formation of the Milky Way
In this paper we adopt a chemical evolution model, which is an improved version of the Chiappini, Matteucci, & Gratton model, assuming two main accretion episodes for the formation of the Galaxy, the
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 the
A survey of interstellar H I from L-alpha absorption measurements. II
The Copernicus satellite surveyed the spectral region near L alpha to obtain column densities of interstellar HI toward 100 stars. The distance to 10 stars exceeds 2 kpc and 34 stars lie beyond 1
