We observed a 400 square degree region centred on the Galactic Centre with the Murchison Widefield Array (MWA) between 103 and 133\\,MHz targeting 28 known molecular species that have significant transitions. The results of this survey yield tentative detections of nitric oxide (NO) and the mercapto radical (SH). Both of these molecules appear to be associated with evolved stars.", "revisions": [ { "version": "v1", "updated": "2017-07-19T10:39:59.000Z" } ], "analyses": { "keywords": [ "murchison widefield array", "first look", "survey yield tentative detections", "square degree region", "low radio frequencies" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable" } } }
