Cosmology at 1 and 2 mm

James Aguirre

The advent of broadband bolometer cameras in the 1 and 2 mm windows with resolution < 1 arcmin allows the study of two important classes of cosmological objects. The 1 mm band is primarily sensitive to dusty, high-redshift, star-forming galaxies and / or AGN (the so-called submillimeter galaxies), whose redshift distribution likely peaks at z ~ 2.5. The 2 mm band is primarily sensitive to Sunyaev-Zel'dovich galaxy clusters, whose redshift distribution is not well known, but is believed to peak at around z ~ 0.4. In this talk, I will discuss placing both of these classes of objects in their cosmological context by combining them with deep, multiwavelength surveys which can help constrain their redshift distribution, environment, and relation to the dark matter potential. I will take as my specific example recent Bolocam results from the COSMOS survey.
