Ultra-high resolution hydrodynamic simulations using 1024$^3$ grid points are performed of early supernova burst in a forming galaxy, with properties similar to those inferred for Lyman \ensuremathα emitters (LAEs) and Lyman Break Galaxies (LBGs). We...

Recently discovered large-scale structure of Lyman \ensuremathα emitters (LAEs) raises a novel challenge to the cold dark matter (CDM) cosmology. The structure is extended over more than 50 Mpc at redshift z = 3.1, and exhibits a considerably weak an...
