Main Point:

Researchers have presented the first set of maps and band-merged catalog from the Herschel Stripe 82 Survey (HerS). The data is publicly available at http://www.astro.caltech.edu/hers/.

Herschel Space Observatory:

It was the observatory launched by European Space Agency (ESA) and remained active from 2009 to 2013. It has the largest single mirror of about 3.5-metres in diameter that was able to collect information in the far infrared and submillimetre wavebands (55–672 µm) from some of the coldest and most distant objects in the Universe.

It has Spectral and Photometric Imaging Receiver (SPIRE) instrument enabling the scientists to study very distant galaxies and to study the earliest stages of star formation. It also helped scientists to the study the formation and early evolution of Active galactic nucleus (AGNs) and quasars, to determine the formation of the massive black holes in distant galaxies.

Herschel Stripe 82 Survey (HerS):

HerS helped scientists to study the redshift distribution of intensities of infrared emitting dusty star-forming galaxies and AGN. It was designed to give the rich set of ancillary data in the SDSS Stripe 82.

Maps and band-merged catalog from the Herschel Stripe 82 Survey (HerS) can be found on the website http://www.astro.caltech.edu/hers/HerS_Home.html. Submillimeter maps at 250, 350, and 500μm, have been added to this catalog. “These bands are sensitive to far-infrared emission from dusty star-forming galaxies and AGN from intermediatehigh, and very high redshifts.  IR-emission, as a direct tracer of star-formation, is a sensitive probe of the star-formation history of the Universe; and in concert with existing ancillary data, can identify the populations responsible for the extragalactic background light,” wrote on the website for catalog.
