Query: Search for sub-mm, mm and radio continuum emission from Extremely Red
  Objects   We present the results of sub-mm, mm (850 um, 450 um and 1250 um) and radio
(1.4 and 4.8 GHz) continuum observations of a sample of 27 K-selected Extremely
Red Objects, or EROs, (14 of which form a complete sample with K < 20 and I-K >
5) aimed at detecting dusty starbursts, deriving the fraction of UltraLuminous
Infrared Galaxies (ULIGs) in ERO samples, and constraining their redshifts
using the radio-FIR correlation. One ERO was tentatively detected at 1250 um
and two were detected at 1.4 GHz, one of which has a less secure identification
as an ERO counterpart. Limits on their redshifts and their star forming
properties are derived and discussed. We stacked the observations of the
undetected objects at 850 um, 1250 um and 4.8 GHz in order to search for
possible statistical emission from the ERO population as a whole, but no
significant detections were derived either for the whole sample or as a
function of the average NIR colours. These results strongly suggest that the
dominant population of EROs with K < 20 is not comprised of ULIGs like HR 10,
but is probably made of radio-quiet ellipticals and weaker starburst galaxies
with L < 10^{12} L_sun and SFR < 100 M_sun/yr.
