Confirmation of X-ray Absorption by Warm-hot Intergalactic Medium in the Sculptor Wall
Published 2011“…In a previous paper, we reported a 3σ detection of an absorption line from the warm-hot intergalactic medium (WHIM) using the Chandra and XMM X-ray grating spectra of the blazar H2356-309, the sight line of which intercepts the Sculptor Wall, a large-scale superstructure of galaxies at z ~ 0.03. …”
