Description
Deep far-infrared photometric surveys studying galaxy evolution and the
nature of the cosmic infrared background are a key strength of the
Herschel mission. We describe the scientific motivation for the PACS
Evolutionary Probe (PEP) guaranteed time key program and its role within
the entire set of Herschel surveys, and the field selection that
includes popular multiwavelength fields such as GOODS, COSMOS, Lockman
Hole, ECDFS, and EGS. We provide an account of the observing strategies
and data reduction methods used. An overview of first science results
illustrates the potential of PEP in providing calorimetric star
formation rates for high-redshift galaxy populations, thus testing and
superseding previous extrapolations from other wavelengths, and enabling
a wide range of galaxy evolution studies.
Herschel is an ESA space observatory with science instruments provided
by European-led Principal Investigator consortia and with important
participation from NASA.

Evolution of Galaxies
Galaxy evolution is a crucial topic in modern extragalactic astrophysics, linking cosmology to the Local Universe. Their study requires collecting statistically significant samples of galaxies of different luminosities at different distances. It implies the ability to observe faint objects using different techniques, and at different wavelengths
