===================================================================== ==> in this proposal, more time is being requested for fmirabel.early ===================================================================== the aim of this proposal is to complete and extend the open time search for starbursts in cluster environments at epochs close to their formation. it is based on the strong probability that elliptical galaxies went through an infrared luminous phase at redshifts of z = 3-5, and the expectation that infrared quasars and damped lyman alpha systems are the light-houses that will guide us to the large concentrations of matter in the early epochs of the universe. the quick analysis of 10x10 arc min deep survey with cam-lw10 at 12 microns around two quasars at z = 3.4 and z = 3.8 revealed about 40 sources per field (5 sigma), half of them with no counterparts in the palomar plates. although the nature of these sources is still unknown, preliminary results from ground based observations at other wavelengths suggest that many of the isocam sources are in fact staburst galaxies at redshifts >virgul 1.3. to know the broad band spectral index of the newly found sources we propose observations with isocam-lw2 at 7 microns and phot-22 at 90 microns. given the succes of this observational program we wish to extend the 10x10 arc min survey to other dusty quasars and damped systems at z > 1.6. we have selected 7 dusty quasars and 4 striking damped lyman alpha systems to be mapped with the isocam lw2 and lw10 filters, and isophot at 90 microns.

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.
