Herschel Multi-tiered Extragalactic Survey (HerMES) Overview
HerMES Overview HerMES Primary Data Access HerMES Catalogs


The Herschel Multi-tiered Extragalactic Survey (HerMES, KPGT_soliver1) is a legacy programme designed to map a set of nested fields totalling 380 deg^2. Fields range in size from 0.01 to 20 deg^2, using the Herschel Spectral and Photometric Imaging Receiver (SPIRE) [at 250, 350 and 500 microns] and the Herschel Photodetector Array Camera and Spectrometer (PACS) [at 100 and 160 microns], with an additional wider component of 270 deg^2 with SPIRE alone. These bands cover the peak of the redshifted thermal spectral energy distribution from interstellar dust and thus capture the reprocessed optical and ultraviolet radiation from star formation that has been absorbed by dust, and are critical for forming a complete multiwavelength understanding of galaxy formation and evolution. In many fields, PACS maps are available from the PACS Evolutionary Probe (PEP) survey.
