Even if the wind is mild and not strong enough to strip the gas disk, the ram pressure disturbs orbits of the inter-arm gas significantly. This results in asymmetric dense molecular arms in the inner few kpc region of a galaxy. This mechanism would explain the asymmetric CO gas distributions in the central regions often observed in Virgo spirals.", "revisions": [ { "version": "v1", "updated": "2002-01-08T09:44:39.000Z" } ], "analyses": { "keywords": [ "central regions", "spiral galaxies", "ram-ppressure effects", "intracluster medium", "asymmetric dense molecular arms" ], "tags": [ "journal article" ], "publication": { "doi": "10.1093/pasj/54.1.33" }, "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable", "inspire": 595483 } } }
