we propose to observe br_alpha and br_beta line emission from a sample of closely-interacting galaxy pairs using isosws. this will provide information on both the extinction and the ionizing flux in the starbursts contained in these systems, which may have extinction as high as av virgul 50. the data will be compared with the mir and fir maps obtained using isocam and isopht (approved iso ot proposal cxu_ss01: mapping ir enhancements in closely interacting spiral-spiral pairs). our ultimate goal is to answer the question how the galaxy-galaxy interactions stimulate the violent starbursts in colliding galaxy pairs: through disk-disk collision or through gravitational tidal effects, or both?

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.
