Abstract

Higher order clustering statistics of Lyα forest provide a unique probe to study non-gaussianity in Intergalactic matter distribution up to high redshifts and from large to small scales. The author presents a brief review of his work studying the spatial clustering properties of Lyα absorbers, with emphasis on 3-point statistics. The observational side of this involves redshift-space clustering of low-z (z<0.48) and high-z (1.7
