cds-question@unistra.frgalaxy-clustersspectroscopyx-ray-sourcesMany of the "missing" baryons are expected to reside in the warm-hot intergalactic medium (WHIM) in the Cosmic-Web filaments, that connect clusters of galaxies. SRG/eROSITA performance verification (PV) observations covered about 15 square degrees of the A3391/95 system and have revealed a ~15Mpc continuous soft emission, connecting several galaxy groups and clusters. Aim. We aim to characterize the gas properties in cluster outskirts (R500<r<R200) and in the detected inter-cluster filaments (>R200) and to compare them to predictions. We performed the X-ray image and spectral analyses using the eROSITA PV data to assess the gas morphology and properties in the outskirts and the filaments in the directions of the previously detected Northern and Southern Filament. We constructed the surface brightness profiles using the particle-induced background subtracted, exposure, and Galactic absorption corrected eROSITA products in the soft band (0.3-2.0keV). We constrained the temperatures, metallicities, and electron densities through X-ray spectral fitting and compared them with the expected properties of the WHIM. We took particular care of the foreground.2024A&A...681A.108Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/681/A108CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/647/A3 : Abell 3391-Abell 3395 ASKAP/EMU image (Brueggen+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/681/A108https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/681/A108http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/681/A108https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/681/A108https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/681/A108http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/681/A108GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/681/A108/list (Informations on fits image)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/681/A108/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/681/A108/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/681/A108/list?GETtext/xml+votable180.050000true96.7-54.10.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/681/A1086/39077https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/681/A108?format=asciiX-raydefaultJ/A+A/681/A108/listInformations on fits imagerecnoRecord number assigned by the VizieR team.
