| Title | The Varied Nature of MAMBO SMGs in the COSMOS Field |
| Speaker | Manuel Aravena, National Radio Astronomy Observatory | | Abstract | In the course of our MAMBO 1.2 mm survey of the COSMOS field we have found
a
sample of 25 bright SMGs. While most of these sources appear to fit well
within
the scenario of typical massive luminous bright star-forming galaxies at
typical
redshifts of ~ 2, some of them appear to be rare objects either in the
transition
between a starburst to a QSO phase, at very high redshift given their lack
of radio
counterparts or embedded in substantial overdensities of massive galaxies
at z~1.5-2.0.
In this talk, I will present IRAM 30m, PdBI and SMA observations that
point to this very
varied nature of some of the most massive systems in the early Universe. |
