the main aim is to study the effects of the presence of a nearby companion, and of a central bar (i.e. the effects of gravitational perturbations) on the gas properties and star-formation activity in spiral galaxies. this kind of statistical study has been carried out in the radio-continuum emission, in halpha and in co emission: the inter-comparison of these results with fir lines will allow a deeper understanding of large-scale physical processes leading to star formation.

Mission Description
The Infrared Space Observatory (ISO) was the world's first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
