Spatial resolution bias in the mid-infrared Starburst/AGN classification

O. Laurent, I. F. Mirabel, V. Charmandaris +4

We present the effects of limited spatial resolution to the observed mid-infrared (MIR) spectrum of an active galactic nucleus (AGN) surrounded by a disk with massive star forming…

Searching for AGN signatures in Mid-IR Spectra: The case of NGC1068

O. Laurent, I. F. Mirabel, V. Charmandaris +3

We present mid-IR observations of the prototypical Seyfert 2 galaxy NGC 1068 obtained with ISOCAM between 5 and 16micron. The proximity of this galaxy coupled with the spectro-imag…

IRS: the Infrared Spectrograph on SIRTF

J. Houck, J. van Cleve, B. Brandl +3

The Infrared Spectrograph (IRS)is one of the three instruments on board the Space Infrared Telescope Facility (SIRTF) to be launched in December 2001. The IRS will provide high res…

The Mid-Infrared Spectra of Interacting Galaxies: From ISO to SIRTF

V. Charmandaris, O. Laurent, I. F. Mirabel +2

We present mid-infrared (5--16micron) images and spectra of a sequence of interacting galaxies, observed by ISOCAM. The galaxies were selected as being at progressive stages in the…

First Detection of Molecular Gas in the Shells of CenA

V. Charmandaris, F. Combes, J. M. van der Hulst

Shells are faint arc-like stellar structures, which have been observed around early type galaxies and are thought to be the result of an interaction. HI gas has recently been detec…
