RESUMEN
ABSTRACT
The completion of the construction and commissioning of the Gran Telescopio Canarias (GTC) and the Gran
Telescopio Milimetrico (GTM) have similar schedules. From 2005 onwards, the GTC and the GTM will
begin scienti c observations, conducting spectroscopic and imaging studies with unprecedented sensitivity at
IR, mid-IR and mm wavelengths. Submm surveys with SCUBA have discovered an important population of
luminous, starburst galaxies. The GTM, with a mapping speed 100 faster than SCUBA, will provide more
extensive mm-wavelength surveys with greater sensitivity and higher resolution. The redshift distribution
of this strongly-evolving population of submm sources (which FIR{radio photometric redshifts suggest peaks
at z ' 3), their star formation history, and AGN fraction all remain poorly constrained. In this paper we
summarise a possible \Key Project" that combines coordinated and collaborative surveys on the GTC and
GTM. Follow-up observations of mm-selected galaxies that utilise the unique IR imaging and multi-object
spectroscopic capabilities of EMIR, and the mid-IR sensitivity of CanariCam are described.
