More Information on the Base Resource

The Herschel Extragalactic Legacy Project (HELP) intends to produce a multi-wavelength, comprehensive data set of the galaxy population at high redshift. The Herschel Space Observatory has the unique property of being able to probe the presence of star formation in extremely dusty galaxies through observations of the far infra-red and sub-millimetre portion of the electromagnetic spectrum. However, Herschel has relatively poor spatial resolution, making it difficult to disentangle which galaxies are responsible for what amount of flux.

HELP aims to robustly address this issue with the use of as many complimentary data sets as possible. With the inclusion of data at shorter wavelengths (such as the optical, radio and near-infra-red), which have much higher spatial resolution, the deblending of Herschel flux into component parts can be undertaken in a much more robust, informed manner. The ultimate goal of HELP is to produce a multi-wavelength data set, which will be easy to use so that astronomers not currently used to working with Herschel data or high redshift surveys could make use of the statistical samples found within the HELP catalogue.

These are the Herschel SPIRE catalogues from HELP.
