Abstract / Description of output
We present a joint analysis of the overlapping Balloon-borne Large
Aperture Submillimetre Telescope (BLAST) 250, 350, 500um, and LABOCA
870um observations [from the LABOCA ECDFS Submm Survey (LESS) survey] of
the Extended Chandra Deep Field-South. Out to z~3, the BLAST filters
sample near the peak wavelength of thermal far-infrared (FIR) emission
from galaxies (rest-frame wavelengths ~60-200um), primarily produced by
dust heated through absorption in star-forming clouds. However,
identifying counterparts to individual BLAST peaks is very challenging,
given the large beams [full-width at half-maximum (FWHM) 36-60 arcsec].
In contrast, the ground-based 870um observations have a significantly
smaller 19 arcsec FWHM beam, and are sensitive to higher redshifts
(z~1-5, and potentially beyond) due to the more favourable negative
K-correction. We use the LESS data, as well as deep Spitzer and VLA
imaging, to identify 118 individual sources that produce significant
emission in the BLAST bands.
