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. To verify our initial detection, we obtained a deep (500 ks), follow-up exposure of H2356-309 as part of the Cycle-10Chandra Large Project Program. From a joint analysis of the Cycle-10 and previous… Expand
Detecting the warm-hot intergalactic medium through X-ray absorption lines
The warm-hot intergalactic medium (WHIM) at temperatures 1E5-1E7 K is believed to contain 30-50% of the baryons in the local universe. However, all current X-ray detections of the WHIM at redshiftsExpand

AN X-RAY WHIM METAL ABSORBER FROM A MPC-SCALE EMPTY REGION OF SPACE
We report a detection of an absorption line at {approx}44.8 A in a >500 ks Chandra HRC-S/LETG X-ray grating spectrum of the blazar H 2356-309. This line can be identified as intervening C V-K{alpha}Expand
Detection of a Transient X-ray Absorption Line Intrinsic to the Bl Lacertae Object H 2356-309

The effect of feedback on the emission properties of the warm—hot intergalactic medium
At present, 30–40 per cent of the baryons in the local Universe is still undetected. According to theoretical predictions, this gas should reside in filaments filling the large-scale structure (LSS)Expand
