cds-question@unistra.frh-i-line-emissiongalaxy-planesmilky-way-galaxyradio-continuum-emissionh-ii-regionsinterstellar-mediumA catalog of candidates for the Galactic Worms that are possibly the walls surrounding the superbubbles is compiled; 118 isolated structures that appear both in HI and in IR (60 and 100{mu}m). 52 are possibly associated with HII regions. It is found that the 100-{mu}m emissivity increases systematically toward the Galactic interior, which is consistent with the increase of the general interstellar radiation field. The 100-{mu}m emissivity of the structures associated with the HII regions is larger than that of the structures without associated HII regions. The 60-100{mu}m ratio is large, 0.28+/-0.03, which may indicate that the grains associated with the atomic gas have a relatively large population of small grains. 35 structures appear in the 408MHz continuum. The IR and the radio continuum properties suggest that the 408MHz continuum emission in those structures is very likely thermal. The implications of these results on the ionization of gas far from the Galactic plane are discussed.1992ApJ...390..108Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/390/108CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/390/108https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/390/108http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/390/108https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/390/108https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/390/108http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/390/108GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/390/108/table2 (Catalog of Worm Candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/390/108/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/390/108/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/390/108/table2?GETtext/xml+votable180.050000true272.61-31.440.0055555555555555566/1394 1505 1774 2555 2933 2998 3037 3245 3366 3608 3637 3841 12840 12946 12982 13004 13292 14014 14110 14156 14202 14232 14237 14248 14366 14421 14477 14752 15459 15512 15560 21533 21737 22088 22124 22312 23866 23949 24012 24492 24500 28708 28726 28766 28770 28882 28886 29110 29144 29153 29175 29185 29212 29308 29444 29450 29497 29514 29526 29556 29860 30123 30273 30322 30341 30385 30444 30462 30500 30569 30577 30614 30667 32022 32107 32123 37193 37312 37959 38051 38433 38467 38504 39212 39389 39421 39949 39970 39987 40452 40482 40582 40599 41453 41523 41573 41611 41626 41711 41735 41793 41798 41923 42120 42127 42190 42302 42315 42361 42484 42581 42595 42755 42865 43051 43097 43115 43152https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/390/108?format=asciiRadiodefaultJ/ApJ/390/108/table5Worm candidates near HII regionsn_GW[a, b] Notes (1)meta.notecharrecnoRecord number assigned by the VizieR team.
