cds-question@unistra.frsupernova-remnantsspectroscopyThe discovery of amino acids in meteorites fallen to Earth and the detection of glycine, the simplest of them, in samples returned from a comet to Earth strongly suggest that the chemistry of the interstellar medium is capable of producing such complex organic molecules and that they may be widespread in our Galaxy. Our goal is to investigate the degree of chemical complexity that can be reached in the interstellar medium, in particular in dense star-forming regions. We performed an unbiased, spectral line survey toward Sgr B2(N) and (M), two regions where high-mass stars are formed, with the IRAM 30m telescope in the 3mm atmospheric transmission window. Partial surveys at 2 and 1.3mm were performed in parallel. The spectra were analyzed with a simple radiative transfer model that assumes local thermodynamic equilibrium but takes optical depth effects into account.2013A&A...559A..47Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/559/A47CatalogResearchIsServedByTAP VizieR generic 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/482/179 : Interferometric study of SgrB2(N) (Belloche+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/559/A47https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/559/A47http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/559/A47https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/559/A47https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/559/A47http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/559/A47GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/559/A47/b2n_ids1List of line identifications at 1mm for Sgr B2(N)recnoRecord number assigned by the VizieR team.
