Query: The Herschel view of the dominant mode of galaxy growth from z=4 to the
  present day   We present an analysis of the deepest Herschel images in four major
extragalactic fields GOODS-North, GOODS-South, UDS and COSMOS obtained within
the GOODS-Herschel and CANDELS-Herschel key programs. The picture provided by
10497 individual far-infrared detections is supplemented by the stacking
analysis of a mass-complete sample of 62361 star-forming galaxies from the
CANDELS-HST H band-selected catalogs and from two deep ground-based Ks
band-selected catalogs in the GOODS-North and the COSMOS-wide fields, in order
to obtain one of the most accurate and unbiased understanding to date of the
stellar mass growth over the cosmic history. We show, for the first time, that
stacking also provides a powerful tool to determine the dispersion of a
physical correlation and describe our method called "scatter stacking" that may
be easily generalized to other experiments. We demonstrate that galaxies of all
masses from z=4 to 0 follow a universal scaling law, the so-called main
sequence of star-forming galaxies. We find a universal close-to-linear slope of
the logSFR-logM* relation with evidence for a flattening of the main sequence
at high masses (log(M*/Msun) > 10.5) that becomes less prominent with
increasing redshift and almost vanishes by z~2. This flattening may be due to
the parallel stellar growth of quiescent bulges in star-forming galaxies.
Within the main sequence, we measure a non varying SFR dispersion of 0.3 dex.
The specific SFR (sSFR=SFR/M*) of star-forming galaxies is found to
continuously increase from z=0 to 4. Finally we discuss the implications of our
findings on the cosmic SFR history and show that more than 2/3 of present-day
stars must have formed in a regime dominated by the main sequence mode. As a
consequence we conclude that, although omnipresent in the distant Universe,
galaxy mergers had little impact in shaping the global star formation history
over the last 12.5 Gyr.
