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…
Mid-IR imaging of Toomre's Merger Sequence
V. Charmandaris, O. Laurent, I. F. Mirabel +1
We present results on mid-IR (5--16micron) spectral imaging of a sequence of interacting galaxies, observed by ISOCAM. The galaxies are part of the well known Toomre's ``merger seq…
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…
