Description detection of primeval galaxies is a direct approach to understand the formation of galaxies, galaxy clusters, and large-scale structure of the universe. it was suggested that a galaxy in its first star-forming phase would be a strong ly-alpha emitter; a sfr would be 1000 m(solar)/yr with l = 3 x 10 ^ 11 m(solar)/yr, if a typical elliptical galaxy with a mass of 3 x 10 ^ 11 m(solar) was formed in 0.3 gyr. however, no such population has been unambiguously identified despite of intensive ly-alpha search campaigns. if primeval galaxies are luminous as suggested, but obscured by dust, iso can provide the unique opportunity to investigate this hypothesis. hence, we propose to search for primeval galaxies in 11 fields centered on known high-redshift objects by conducting isocam lw2 (6.7 um) imaging and isophot-c c_90 (90 um) and c_160 (160 um) mapping. we choose to use known high-redshift objects as markers of possible clusters or protoclusters rather than attempt a completely unbiased search, since the purpose is to detect any kind of primeval galaxies. for this, a qso with damped ly-alpha systems is an ideal object, since multiple markers are available in that direction.

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.
