cds-question@unistra.frx-ray-sourcesredshiftedWe have identified a large-scale structure traced by galaxies at z=0.8, within the Lockman Hole, by means of multi-object spectroscopic observations. By using deep XMM images we have investigated the soft X-ray emission from the Warm-Hot Intergalactic Medium (WHIM) expected to be associated with this large-scale structure and we set a tight upper limit to its flux in the very soft 0.2-0.4keV band. The non-detection requires the WHIM at these redshifts to be cooler than 0.1keV. Combined with the WHIM emission detections at lower redshift, our result indicates that the WHIM temperature rapidly decreases with redshift, as expected in popular cosmological models.2005A&A...434..801Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/434/801CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/434/801https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/434/801http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/434/801https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/434/801https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/434/801http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/434/801GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/434/801/catalog (Catalogue of objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/434/801/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/434/801/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/434/801/catalog?GETtext/xml+votable180.050000true163.424041757.35821110.0055555555555555566/6069 6112https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/434/801?format=asciiX-rayOpticaldefaultJ/A+A/434/801/catalogCatalogue of objectsrecnoRecord number assigned by the VizieR team.
