Proposal Title: Local Turbulent Disks: analogs of high­redshift vigorously star­forming disks
and laboratories for galaxy assembly
ABSTRACT:
We request Arecibo observations to measure the neutral gas mass of 35 low redshift galaxies we have discovered
with unique kinematic and star­formation properties. These systems appear to closely resemble massive highly
turbulent disk galaxies at z­2 revealed by Adaptive Optics (AO) Integral Field Spectroscopic (IFS) observations.
Such massive turbulent disks are relatively common at high redshift but until our study no nearby counterparts for
these galaxies were known. The selected targets form a unique sample of local laboratories to study one of the most
fundamental modes of galaxy growth and star formation. The systems are predicted to have high atomic and
molecular gas fractions of 30­50% (or more) as has been observed in z­2 disks. Observations of the atomic gas with
Arecibo will provide a complete tally of the gas reservoir in these turbulent disk galaxies and complement our
current observing programs with Gemini/GMOS, Herschel, HST and Keck/OSIRIS.
