Extragalactic Spectroscopy with SIRTF/IRS
B. Brandl, V. Charmandaris, K. Uchida +1
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 re…
Smoke in the "Smoke Rings": ISO Observations of Dust in Collisional Ring Galaxies
P. N. Appleton, V. Charmandaris, C. Horellou +2
Collisional ring galaxies probably result from a head-on collision between a compact companion galaxy and a gas-rich disk system. We present a review of the discovery of warm dust…
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…
Formation of Gaseous Shells
F. Combes, V. Charmandaris
HI observations have revealed in several shell galaxies the presence of gaseous shells slightly displaced from the stellar shells radially, in the outward direction. We propose a m…
