SINGS: The SIRTF Nearby Galaxies Survey
Kewley, Lisa J.; Gordon, Karl D.; Calzetti, Daniela +20 more
The SIRTF Nearby Galaxy Survey is a comprehensive infrared imaging and spectroscopic survey of 75 nearby galaxies. Its primary goal is to characterize the infrared emission of galaxies and their principal infrared-emitting components, across a broad range of galaxy properties and star formation environments. SINGS will provide new insights into th…
Titan's atmosphere from ISO mid-infrared spectroscopy
Lellouch, E.; Feuchtgruber, H.; Coustenis, Athena +5 more
We have analyzed Titan observations performed by the Infrared Space Observatory (ISO) in the range 7-30 µm. The spectra obtained by three of the instruments on board the mission (the short wavelength spectrometer, the photometer, and the camera) were combined to provide new and more precise thermal and compositional knowledge of Titan's stra…
A Uniform Database of 2.4-45.4 Micron Spectra from the Infrared Space Observatory Short Wavelength Spectrometer
Sloan, G. C.; Kraemer, Kathleen E.; Price, Stephan D. +1 more
We present a complete set of all valid SWS full-scan 2.4-45.4 µm spectra processed and renormalized in as uniform a manner as possible. The processing produces a single spectrum for each observation from the 288 individual spectral segments, which are the most processed form available from the ISO archive. The spectra, and the programs used …
Steps toward interstellar silicate mineralogy. VII. Spectral properties and crystallization behaviour of magnesium silicates produced by the sol-gel method
Mutschke, H.; Henning, Th.; Posch, Th. +2 more
Amorphous silicate particles are generally assumed to be the main dust component in the envelopes of oxygen-rich evolved stars and may be considered the precursors of the pure crystalline enstatite and forsterite particles detected by ISO. We present optical constants in the broad wavelength range 0.2-500 mu m for a unique series of pure amorphous…
The [C II] 158 Micron Line Deficit in Ultraluminous Infrared Galaxies Revisited
Lutz, D.; Genzel, R.; Sturm, E. +5 more
We present a study of the [C II] 157.74 µm fine-structure line in a sample of 15 ultraluminous infrared (IR) galaxies (IR luminosity LIR>=1012Lsolar ULIRGs) using the Long Wavelength Spectrometer (LWS) on the Infrared Space Observatory (ISO). We confirm the observed order of magnitude deficit (compared to …
ISM properties in low-metallicity environments. II. The dust spectral energy distribution of NGC 1569
Bernard, J. -P.; Madden, S. C.; Galliano, F. +3 more
We present new 450 and 850 mu m SCUBA data of the dwarf galaxy NGC 1569. We construct the mid-infrared to millimeter SED of NGC 1569, using ISOCAM, ISOPHOT, IRAS, KAO, SCUBA and MAMBO data, and model the SED in order to explore the nature of the dust in low metallicity environments. The detailed modeling is performed in a self-consistent way, synt…
Composition and origin of the atmosphere of Jupiter - an update, and implications for the extrasolar giant planets
Wong, M. H.; Atreya, S. K.; Owen, T. C. +2 more
New developments have led to this update of the composition and origin of Jupiter's atmosphere that were originally discussed in our Planet. Space Sci. 47 (1999) 1243 paper. Since Jupiter can provide important insight into the atmospheres of extrasolar giant planets (EGP), we also discuss here the possible implications of the first detection of an…
The origin of crystalline silicates in the Herbig Be star HD 100546 and in comet Hale-Bopp
Waters, L. B. F. M.; Dominik, C.; de Koter, A. +1 more
We have investigated the spatial distribution, and the properties and chemical composition of the dust orbiting HD 100546. This system is remarkably different from other isolated Herbig Ae/Be stars in both the strength of the mid-IR excess and the composition of the circumstellar dust. To explain spectral features and the amount of mid-IR dust emi…
Grain growth in the inner regions of Herbig Ae/Be star disks
Waters, L. B. F. M.; Dominik, C.; van Boekel, R. +4 more
We present new mid-infrared spectroscopy of the emission from warm circumstellar dust grains in Herbig Ae/Be stars. Our survey significantly extends the sample that was studied by Bouwman et al. (2001). We find a correlation between the strength of the silicate feature and its shape. We interpret this as evidence for the removal of small (0.1 mu m…
The ISO view of Palomar-Green quasars
Meisenheimer, K.; Krause, O.; Lemke, D. +8 more
Mining the ISO data archive we provide the complete ISO view of PG quasars containing 64 infrared spectral energy distributions between 5 and 200 mu m. About half of the sample was supplemented by MAMBO and SCUBA (sub-)millimetre data. Since the PG quasars were selected optically, the high infrared detection rate of more than 80% suggests that eve…
