(Sub)Millimeter Galaxies • CFIRB: approximately = extragal. Opt./UV • 100s of galaxy candidates detected • High z: <zopt> 2.4 • High implied luminosities (L~1013 Lsolar) • & SFRs (~103 Msolar/year) • Masses from CO: molecular ~1010 Msolar • dynamical ~1011 Msolar
Bolocam Candidates—CSO 324 square arcminutes (0.25 sq. deg. survey of COSMOS underway) Pixel Sensitivity Histogram 17 Galaxy Candidates Jackknife Histogram = 1.1 mm (Laurent et al., ApJ, 623, 742)
P(D) Fluctuation Analysis N(S) S-δ δ = 2.7 +0.18/-0.15 (1mJy Sν 10mJy) N(>1 mJy) = 940 +50/-140 deg-2 (95% confidence) • Results (Maloney et al. 2005) • δ similar to theoretical expectations (Blain et al. 2002) • Although integral number counts N(>1 mJy) 2-3 lower than 1.2 mm observations (Greve et al. 2004) & models Wider & deeper observations underway will more fully characterize the number counts
These Five Galaxies • T: 20 < T < 40 K • L: 1.0-1.21013 L☼, 1.31011 L☼ • : 350 m essential for T and L; 850 m – 1.2 mm for M 350 m Follow Up 5 Galaxies All redshifted to z=2 • Large FOV Telescopes • Surveys, photometry • Redshifts • SMA/ALMA • Astrometry/IDs • SEDs • Morphologies (Laurent et al. and Kovacs et al. in prep.)
Molecular Gas Redshifts: Z-Spec @ CSO First light June 2005! • Z-Spec • R~800 km s-1 • 160 60-mK bolometers + waveguide-coupled grating This spectrum is not calibrated and the error bars are preliminary; do not consider it quantitatively.
