As most results in extra galactic astrophysics this one also depends on the cosmological model used. The actual paper linked in the article describes it well: &quot;The cosmic optical background (COB) is the average flux of visible light photons averaged over the volume of the observable Universe. It reflects, at least in part, an integral over the cosmological history of star formation occurring in recognizable galaxies, proto-galaxies, and star clusters (Conselice et al. 2016), as well as mass accretion by black holes (BHs) associated with the systems.&quot;…</p><p><a href="https://hackerpaper.kaipfister.de/p/2011.03052/">Paper and discussion history</a>.
