cds-question@unistra.frmolecular-cloudsradio-astronomyradio-continuum-emissionspectroscopyh-ii-regionsnebulaeWe present a 30-50GHz survey of Sagittarius B2(N) conducted with the Australia Telescope Compact Array (ATCA) with 5 - 10 arcsec resolution. We analyze the spectra towards three HII regions that have foreground molecular gas in Sgr B2. Towards the most line-dense region, we detect >500 spectral line components, >90% of which are assigned to H and He recombination lines and 53 firmly identified molecular species (not including isotopologues). The data reveal extremely subthermally excited molecular gas in Sgr B2 absorbing against the continuum background, as well as molecular line emission from two hot cores in Sgr B2(N). They also also contain line-of-sight absorption by ~15 molecules observed in translucent gas in the Galactic Center, bar, and intervening spiral arm clouds, revealing the complex chemistry and clumpy structure of this gas. Formamide (NH_2_CHO) is detected for the first time in a translucent cloud.2015MNRAS.452.3969Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/452/3969CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/117/427 : Sgr B2 spectral survey (Nummelin+, 1998)J/ApJS/158/188 : Detection of glycolaldehyde toward Sgr B2 (Widicus+, 2005)J/A+A/559/A47 : Sgr B2(N) and Sgr B2(M) IRAM 30m line survey (Belloche+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/452/3969https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/452/3969http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/452/3969https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/452/3969https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/452/3969http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/452/3969GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/452/3969/list (List of fits images and data cubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/452/3969/list?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/452/3969/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/452/3969/list?GETtext/xml+votable180.050000true266.835-28.370.0055555555555555566/28830https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/452/3969?format=asciiOpticalRadiodefaultJ/MNRAS/452/3969/listList of fits images and data cubesrecnoRecord number assigned by the VizieR team.
