Title: First Science from HerMES: the final starbursts in massive galaxies at 0.5<z<1.0
Abstract:
Herschel has now successfully launched, and commenced routine operations. The
multiple far-IR bands of Herschel, coupled with its ability to deeply survey
large areas of sky on rapid timescales, makes it the ideal instrument to
resolve some of the key problems in galaxy formation raised by instruments
such as SCUBA. In this proposal we aim to take the first steps in exploiting
the enormous power of Herschel, by using GMOS to obtain redshifts and
spectral diagnostics for some of the most extreme objects that Herschel
detects in the HerMES guaranteed time survey. These are rare (1 per square
degree) sub-mm bright, optically faint sources at 0.5<z<1, expected to be
objects with star-formation rates exceeding 1000Msun/yr - likely massive
systems undergoing their last major star formation episode. Herschel is the
first observatory that can easily identify such systems and produce
statistically significant samples of them. This proposal represents an
opportunity for Gemini to take an early lead in the exploration of the new
parameter space opened up by Herschel.
