[C II]
Undetected in 38 hrs on JCMT by Bolatto et al. 04
[C II] was detected in over 12 hrs with the 30m to peak intensity 12 (4) mJy; with ALMA it will be 5 sigma in a minute. But J1148 has L=2 x 10^13. With 16 antennas, of course, we could get this in ten minutes.

16. Epoch of “galaxy formation” (z=1.5 – 3)
Submm/radio surveys reveal massive, dusty starburst galaxies at high redshift, often unseen in deepest optical surveys (eg. HDF)
Comparable SFR at z>2 in these “submm galaxies” as optically selected galaxies = formation of large elliptical galaxies?
Combined radio/mm/(near)IR allows for accurate positions, and coarse redshifts
currently limited to extreme starbusts (1000 M_sun/yr)
