cds-question@unistra.frmilky-way-galaxymolecular-cloudsradio-astronomyThe Central Molecular Zone (CMZ) at the center of our Galaxy is the best template to study star formation processes under extreme conditions, similar to those in high-redshift galaxies. We observed on-the-fly maps of para-H_2_CO transitions at 218GHz and 291GHz with the Atacama Pathfinder Experiment (APEX) telescope towards seven Galactic center clouds. From the temperature-sensitive integrated intensity line ratios of H_2_CO(3_21_-2_20_)/H_2_CO(3_03_-2_02_) and H_2_CO(4_22_-3_21_)/H_2_CO(4_04_-3_03_) in combination with radiative transfer models, we produce gas temperature maps of our targets. Our targets have a complex velocity structure that requires a careful disentanglement of the different components. We produce temperature maps for each of the velocity components and show that the temperatures of the components differ, revealing temperature gradients in the clouds.2016A&A...595A..94Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/595/A94CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/595/A94https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/595/A94http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/595/A94https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/595/A94https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/595/A94http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/595/A94GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/595/A94/list (List of fits gas temperature maps)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/595/A94/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/595/A94/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/595/A94/list?GETtext/xml+votable180.050000true266.40371-29.085490.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/595/A946/28827 28830-28831https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/595/A94?format=asciiRadiodefaultJ/A+A/595/A94/listList of fits gas temperature mapsTitleTitle of the FITS filemeta.title;meta.fitsrecnoRecord number assigned by the VizieR team.
