We derive the extinction curve toward the Galactic center (GC) from 1 to 19 {mu}m. We use hydrogen emission lines of the minispiral observed by ISO-SWS and SINFONI. The extinction-free flux reference is the 2 cm continuum emission observed by the Very Large Array. Toward the inner 14'' x 20'', we find an extinction of A{sub 2.166{mu}m} = 2.62 {+-} 0.11, with a power-law slope of {alpha} = -2.11 {+-} 0.06 shortward of 2.8 {mu}m, consistent with the average near-infrared slope from the recent… 
Modeling the infrared extinction toward the galactic center
We model the ~ 1–19 μ m infrared (IR) extinction curve toward the Galactic Center (GC) in terms of the standard silicate-graphite interstellar dust model. The grains are taken to have a power law
The Mid-infrared Extinction Law and its Variation in the Coalsack Nebula
In recent years, the wavelength dependence of interstellar extinction from the ultraviolet (UV) to the near- and mid-infrared (IR) has been studied extensively. Although it is well established that
The Optical/Near-Infrared Extinction Law In Highly Reddened Regions
A precise extinction law is a critical input when interpreting observations of highly reddened sources such as young star clusters and the Galactic Center (GC). We use Hubble Space Telescope
Extinction law at a distance up to 25 kpc toward the Galactic poles
Photometry from the Tycho-2, 2MASS, andWISE catalogues for clump and branch giants at a distance up to 25 kpc toward the Galactic poles has allowed the variations of various characteristics of the
An image of the dust sublimation region in the nucleus of NGC 1068
We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Interferometer. The
Mid-infrared Extinction and Fresh Silicate Dust Toward the Galactic Center
We interpret the interstellar extinction observed toward the Galactic center (GC) in the wavelength range λ = 1–20 μm. Its main feature is the flat extinction at 3–8 μm whose explanation is still a
Properties of Dust Grains Probed with Extinction Curves
Modern data of the extinction curve from the ultraviolet to the near-infrared are revisited to study properties of dust grains in the Milky Way (MW) and the Small Magellanic Cloud (SMC). We confirm
The Panchromatic Hubble Andromeda Treasury. VII. The Steep Mid-Ultraviolet to Near-Infrared Extinction Curve in the Central 200 pc of the M31 Bulge
We measure the extinction curve in the central 200 pc of M31 at mid-ultraviolet to near-infrared wavelengths (from 1928A to 1.5{\mu}m), using Swift/UVOT and HST WFC3/ACS observations in thirteen
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
Detailed Abundances for the Old Population near the Galactic Center: I. Metallicity distribution of the Nuclear Star Cluster
We report the first high spectral resolution study of 17 M giants kinematically confirmed to lie within a few parsecs of the Galactic Center, using R=24,000 spectroscopy from Keck/NIRSPEC and a new
