报告摘要：The extragalactic background light (EBL) from ultra-violet (UV) to far-infrared (far-IR) bands is comprised of the cumulative radiation from all galaxies and active galactic nuclei (AGNs) over the cosmic history. The current measurements of the near-infrared (near-IR) intensity fluctuations suggest an excess in the clustering signal at scales of a few arcminutes compared to the expectations from models of galaxy formation and evolution. This indicates that the EBL may contain faint, extended components missed in ordinary galaxy surveys. In this talk, I will review the possible origins of the anisotropy of near-IR EBL and discuss the potential candidates which can explain this excess.
