Abstract: | We present the results obtained through the various ISO extragalactic deep surveys. Although IRAS revealed the existence of
galaxies forming stars at a rate of a few tens (LIRGs) or even hundreds (ULIRGs) solar masses in the local universe, ISO not
only discovered that these galaxies were already in place at redshift one, but also that they are not the extreme objects
that we once believed them to be. Instead they appear to play a dominant role in shaping present-day galaxies as reflected
by their role in the cosmic history of star formation and in producing the cosmic infrared background detected by the COBE
satellite in the far infrared to sub-millimeter range.
Based on observations with ISO, an ESA project with instruments funded by ESA Member States (especially the PI countries:
France, Germany, The Netherlands, and the United Kingdom), and with the participation of ISAS and NASA. |
