Description being dumb-bell galaxies gravitationally bound systems often found in the deep of cluster potential well, from their study one can deduce information on the clusters formation process and on the evolution of e galaxies in a dense environment. investigation of dust properties in dumb-bells can tell much about the stage of evolution and thermal conditions inside these systems, and, for x-emitting ones, can set more precise constraints on the cooling rate in cooling flows. through iso phot observations of a complete and homogeneous, optically selected sample of 27 dumb-bell cluster galaxies in the southern emisphere we propose to investigate their dust properties to give a reliable estimate of dust mass and temperature inside these systems. with respect to normal bcms, the unusually high detected percentage of radio emission found in our sample, always corresponding to only one of the db components, supports the hypothesis of nuclear activity triggered by gas infall over one of the nuclei: with iso observations we will study the correlations between dumb-bells far infrared, radio and x emission. moreover, dust reflects also the amount of star formation, giving indications on the gas dynamics: high-sensitivity observations of our sample with isocam will permit us to investigate dust distribution inside dumb-bells and to learn something more on the internal dynamical state of these highly dynamically structured galaxies.

Mission Description The Infrared Space Observatory (ISO) was the worlds 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.
