ISOPHOT observations of 3CR quasars and radio galaxies
Ilse M. van Bemmel, Peter D. Barthel, Thijs de Graauw
In order to check for consistency with the radio-loud AGN unification scheme, ISOPHOT data obtained for two small sets of intermediate redshift steep-spectrum 3CR radio galaxies an…
Infrared Observations of Hot Gas and Cold Ice toward the Low Mass Protostar Elias 29
A. C. A. Boogert, A. G. G. M. Tielens, C. Ceccarelli +5
We have obtained the full 1-200 um spectrum of the low luminosity (36 Lsun) Class I protostar Elias 29 in the Rho Ophiuchi molecular cloud. It provides a unique opportunity to stud…
ISO-SWS observations of pure rotational water absorption lines toward Orion-IRc2
C. M. Wright, E. F. van Dishoeck, J. H. Black +4
First detections of thermal water vapor absorption lines have been made toward Orion IRc2 using the Short Wavelength Spectrometer (SWS) on board the Infrared Space Observatory (ISO…
The infrared spectrum of the Be star gamma Cassiopeiae
S. Hony, L. B. F. M. Waters, P. A. Zaal +6
We present the 2.4-45 micrometer ISO-SWS spectrum of the Be star gamma Cas (B0.5 IVe). The spectrum is characterised by a thermal continuum which can be well fit by a power-law S_n…
ISO-SWS observations of interstellar solid 13CO2: heated ice and the Galactic 12C/13C abundance ratio
A. C. A. Boogert, P. Ehrenfreund, P. A. Gerakines +7
We present observations of the stretching mode of 13CO2 ice along 13 lines of sight in the Galaxy, using the Short Wavelength Spectrometer on board of the Infrared Space Observator…
Infrared emission from radio-loud active nuclei
Ilse M. van Bemmel, Peter D. Barthel, Thijs de Graauw
In order to test the unification scheme for double-lobed radio sources, the far-infrared properties of matched samples of radio-galaxies and radio-loud quasars were studied using I…
