| Abstract | Extra-galactic surveys with large submillimeter bolometer cameras discovered a population of dust obscured starbursting galaxies at high redshifts. These submillimeter galaxies (SMGs) are crucial in the stellar build up of the Universe, and their abundance and epoch of formation place important constraints in models of galaxy evolution. Using the Max-Planck Millimeter Bolometer Array (MAMBO) on the IRAM 30 m telescope, we mapped the central 20'x20' of the COSMOS field at 1.2 mm to an rms level of 1 mJy per 11'' beam. We found 15 significant (S/N>4) millimeter sources, 11 of which have a reliable 1.4 GHz Very Large Array (VLA) radio counterpart. Ten more lower significance millimeter sources were identified based on a radio association. We used 24 um data to complement the radio identifications. Using a stacking analysis on the MAMBO map, we estimated that radio (S_nu>45 uJy), 24 um (S_nu>550 uJy) and millimeter sources (S_nu>4 mJy) contribute with about 12% of the total cosmic background radiation at 1.2 mm. more... |
