The silicate absorption profile in the ISM towards the heavily obscured nucleus of NGC 4418 [PDF]
, 2015 The 9.7-micron silicate absorption profile in the interstellar medium provides important information on the physical and chemical composition of interstellar dust grains. Measurements in the Milky Way have shown that the profile in the diffuse interstellar medium is very similar to the amorphous silicate profiles found in circumstellar dust shells ...

On Ultrasmall Silicate Grains in the Diffuse Interstellar Medium [PDF]
, 2000 The abundance of both amorphous and crystalline silicates in very small grains is limited by the fact that the 10 micron silicate emission feature is not detected in the diffuse ISM. On the basis of the observed IR emission spectrum for the diffuse ISM, the observed ultraviolet extinction curve, and the 10 micron silicate absorption profile, we obtain ...

The Origin of the Silicate Emission Features in the Seyfert 2 Galaxy, NGC 2110 [PDF]
, 2009 The unified model of active galactic nuclei (AGN) predicts silicate emission features at 10 and 18 microns in type 1 AGN, and such features have now been observed in objects ranging from distant QSOs to nearby LINERs. More surprising, however, is the detection of silicate emission in a few type 2 AGN.
