Description
Emission at far-infrared wavelengths makes up a significant fraction of
the total light detected from galaxies over the age of Universe.
Herschel provides an opportunity for studying galaxies at the peak
wavelength of their emission. Our aim is to provide a benchmark for
models of galaxy population evolution and to test pre-existing models of
galaxies. With the Herschel Multi-tiered Extra-galactic survey, HerMES,
we have observed a number of fields of different areas and sensitivity
using the SPIRE instrument on Herschel. We have determined the number
counts of galaxies down to ~20 mJy. Our constraints from directly
counting galaxies are consistent with, though more precise than,
estimates from the BLAST fluctuation analysis. We have found a steep
rise in the Euclidean normalised counts <100 mJy. We have directly
resolved ~15% of the infrared extra-galactic background at the
wavelength near where it peaks.
Herschel is an ESA space observatory with science instruments provided
by European-led Principal Investigator consortia and with important
participation from NASA.
