N2 - We present a revised measurement of the optical extragalactic background
light (EBL), based on the contribution of resolved galaxies to the
integrated galaxy light (IGL). The cosmic optical background radiation
(COB), encodes the light generated by star-formation, and provides a
wealth of information about the cosmic star formation history (CSFH). We
combine wide and deep galaxy number counts from the Galaxy And Mass
Assembly survey (GAMA) and Deep Extragalactic VIsible Legacy Survey
(DEVILS), along with the Hubble Space Telescope (HST) archive and other
deep survey datasets, in 9 multi-wavelength filters to measure the COB
in the range from 0.35 μm to 2.2 μm. We derive the luminosity
density in each band independently and show good agreement with recent
and complementary estimates of the optical-EBL from very high-energy
(VHE) experiments. Our error analysis suggests that the IGL and
γ-ray measurements are now fully consistent to within $\sim 10{{\
\rm per\ cent}}$ , suggesting little need for any additional source of
diffuse light beyond the known galaxy population. We use our revised IGL
measurements to constrain the cosmic star-formation history, and place
amplitude constraints on a number of recent estimates. As a consistency
check, we can now demonstrate convincingly, that the CSFH, stellar mass
growth, and the optical-EBL provide a fully consistent picture of galaxy
evolution. We conclude that the peak of star-formation rate lies in the
range 0.066-0.076 M⊙ yr-1 Mpc-3 at
a lookback time of 9.1 to 10.9 Gyrs.
