Fire and Ice: IRS Mid-IR Spectroscopy of IRAS F00183--7111
H. W. W. Spoon, L. Armus, J. Cami +8
We report the detection of strong absorption and weak emission features in the 4--27 micron Spitzer-IRS spectrum of the distant ultraluminous infrared galaxy (ULIRG) IRAS F00183--7…
Mid-infrared spectral evidence for a luminous dust enshrouded source in Arp220
H. W. W. Spoon, A. F. M. Moorwood, D. Lutz +3
We have re-analyzed the 6-12 micron ISO spectrum of the ultra-luminous infrared galaxy Arp220 with the conclusion that it is not consistent with that of a scaled up version of a ty…
Ices in Star-Forming Regions: First Results from VLT-ISAAC
E. F. van Dishoeck, E. Dartois, W. F. Thi +8
The first results from a VLT-ISAAC program on L- and M-band infrared spectroscopy of deeply-embedded young stellar objects are presented. The advent of 8-m class telescopes allows…
The obscured mid-infrared continuum of NGC 4418: a dust- and ice-enshrouded AGN
H. W. W. Spoon, J. V. Keane, A. G. G. M. Tielens +2
We report the detection of absorption features in the 6-8 micron region superimposed on a featureless mid-infrared continuum in NGC 4418. For several of these features this is the…
