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…

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…

The ISOCAM/LW Detector Dark Current Behaviour

A. Biviano, M. Sauvage, P. Gallais +5

We describe the calibration, measurements and data reduction, of the dark current of the ISOCAM/LW detector. We point-out the existence of two significant drifts of the LW dark-cur…

A barred spiral at the centre of the giant elliptical radio galaxy Centaurus A

I. F. Mirabel, O. Laurent, D. B. Sanders +7

We report observations at mid-infrared and sub-millimeter wavelengths of Centaurus A (CenA, NGC 5128), the giant elliptical galaxy that harbors the closest radio loud Active Galact…

Dust in the Wheel: The Cartwheel Galaxy in the Mid-IR

V. Charmandaris, O. Laurent, I. F. Mirabel +5

We present mid-infrared images at and of ``The Cartwheel'' (AM~0035-33), the prototypical collisional ring galaxy. The observations, taken with ISOCAM, reveal the…

The dark side of star formation in the Antennae galaxies

I. F. Mirabel, L. Vigroux, V. Charmandaris +6

We compare mid-infrared images of the Antennae galaxies (NGC 4038/39) from the Infrared Space Observatory, with optical images from the Hubble Space Telescope. The mid-infrared obs…
