On the origin of near-infrared extragalactic background light anisotropy

Gong, Yan; Cooray, Asantha; Matsuura, Shuji +13 more

Extragalactic background light (EBL) anisotropy traces variations in the total production of photons over cosmic history and may contain faint, extended components missed in galaxy point-source surveys. Infrared EBL fluctuations have been attributed to primordial galaxies and black holes at the epoch of reionization (EOR) or, alternately, intrahal…
