The 15 – 20 Micron Spitzer Spectra of Interstellar Emission Features in NGC 7023
We present 15 – 20 µm long-slit spectra, from the Infrared Spectrograph (IRS) on Spitzer, of NGC 7023. We observe recently-discovered interstellar emission throughout the reflection nebula. The 16.4 µm emission feature peaks near the photodissociation front northwest of the star, as do the aromatic emission features (AEFs) at 3.3, 6.2 and 11.3 µm. The 16.4 µm emission feature is thus likely rel...
متن کاملIs SiS 2 the carrier of the unidentified 21 micron emission feature ?
Spectra are presented of SiS2 samples in a variety of crystal forms taken at both room temperature and at 600 K over the wavelength range from 5-25 microns. All spectra show strong features at 22.5 and 9.5 microns as well as less intense bands at 7.5, 8.5, and 12.5 microns. All room temperature spectra also show a feature at 10.7 microns that disappears on heating. One form of SiS2 shows strong...
متن کاملOn the Carriers of the 21 Micron Emission Feature in Post-Asymptotic Giant Branch Stars
The mysterious 21μm emission feature seen in sixteen C-rich proto-planetary nebulae (PPNe) remains unidentified since its discovery in 1989. Over a dozen of materials are suggested as the carrier candidates. In this work we quantitatively investigate eight inorganic and one organic carrier candidates in terms of elemental abundance constraints, while previous studies mostly focus on their spect...
متن کاملMicron Dust Emission from High Redshift Objects
We report observations of a sample of high redshift sources (1.8 ∼< z ∼< 4.7), mainly radio-quiet quasars, at 350μm using the SHARC bolometer camera at the Caltech Submillimeter Observatory. Nine sources were detected (∼> 4σ) and upper limits were obtained for 11 with 350μm flux density limits (3 σ) in the range 30 125mJy. Combining published results at other far-infrared and millimeter wavelen...
متن کاملMicron Dust Emission from High Redshift Quasars
We report detections of six high-redshift (1.8 ≤ z ≤ 6.4), optically luminous, radio-quiet quasars at 350 μm, using the SHARC II bolometer camera at the Caltech Submillimeter Observatory. Our observations double the number of high-redshift quasars for which 350 μm photometry is available. By combining the 350 μm measurements with observations at other submillimeter/millimeter wavelengths, for e...
